+Thank you for taking the time to file a bug report. Please fill in as much
+of the template below as you can. Reports without a reproducer or
+environment details are very hard to triage.
+-->
+
+### Before filing
+
+- [ ] I searched the [existing issues](https://github.com/boostorg/graph/issues?q=is%3Aissue) and did not find a duplicate.
+- [ ] I have reproduced the bug against the `develop` branch or the latest Boost release.
+- [ ] I have a minimal reproducer (or I will paste my full failing code below).
+
+### Boost version
+
+<!--
+You can find the version number in `<boost/version.hpp>`, or by running
+`git log -1` in your local Boost.Graph checkout.
+-->
+
+### Compiler family
+
+- [ ] GCC / g++
+- [ ] Clang / clang++
+- [ ] MSVC (Visual Studio)
+- [ ] Intel / oneAPI
+- [ ] Other (specify below)
+
+Exact compiler version: <!-- e.g. g++ 13.2.0, clang 17.0.6, MSVC 19.39 -->
+
+### Standard library
+
+- [ ] libstdc++
+- [ ] libc++
+- [ ] MSVC STL
+- [ ] Other (specify below)
+
+### Operating system
+
+- [ ] Linux
+- [ ] macOS
+- [ ] Windows
+- [ ] Other (specify below)
+
+### Kind of component affected
+
+- [ ] Graph data structure (e.g. `adjacency_list`, `adjacency_matrix`)
+- [ ] Algorithm (e.g. `dijkstra_shortest_paths`, `breadth_first_search`)
+- [ ] Property map
+- [ ] I/O or file-format reader (e.g. `read_graphml`, `read_graphviz`)
+- [ ] Visitor / event hooks
+- [ ] Other (specify below)
+
+Exact name of the affected component: <!-- e.g. dijkstra_shortest_paths -->
+
+### Steps to reproduce
+
+<!--
+A minimal compiling program that demonstrates the problem is ideal.
+A [Compiler Explorer](https://godbolt.org/z/9Esszr9Ga) link is even better.
+-->
+
+### Expected behavior
+
+### Actual behavior
+
+<!--
+Include compiler error messages or runtime output verbatim, with file and
+line numbers where applicable.
+-->
+
+### Are you willing to help?
+
+- [ ] I'd like to submit a fix as a pull request.
+- [ ] I can help diagnose or test a candidate fix.
+- [ ] I'm only reporting the issue.

+### Before filing

+- [ ] I searched the [existing issues](https://github.com/boostorg/graph/issues?q=is%3Aissue) and did not find a duplicate.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes, and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders responsible for enforcement at `arnaud.becheler -at- gmail.com`. All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the community.

+# Contributing to Boost.Graph
+
+## We are welcoming contributions
+
+- Bug fixes and test cases for them
+- New algorithms (with tests, documentation, complexity notes, and a reference)
+- Documentation, examples, performance work
+- Concept refinements (handle with care as these are API-visible)
+
+## Maintainers
+
+| Maintainer | Role | Focus | Availability | Contact |
+|---|---|---|---|---|
+| **Jeremy W. Murphy** | Principal maintainer. Holds merge authority and final say on design decisions. | Algorithms, technical review, library architecture. 10+ years on BGL. | Part-time, best-effort. | `jeremy.william.murphy -at- gmail.com` |
+| **Arnaud Becheler** | Assistant maintainer. Triage, review, and contributor support; defers to Jeremy on merge decisions. | Documentation, modernization, contributor onboarding. | Full-time, funded by the [C++ Alliance](https://cppalliance.org) to assist Jeremy. | `arnaud.becheler -at- gmail.com` |
+
+The authoritative maintainer list lives in [meta/libraries.json](meta/libraries.json); keep this section in sync with it. Maintainers aim to provide first-pass review on new PRs within two weeks.
+
+## Getting set up
+
+Clone the [Boost superproject](https://github.com/boostorg/boost):
+
+```bash
+git clone --depth 1 https://github.com/boostorg/boost
+cd boost
+git submodule update --init --depth 1
+./bootstrap.sh
+./b2 headers
+```
+
+Then replace `libs/graph/` with your fork:
+
+```bash
+rm -rf libs/graph
+git clone https://github.com/<you>/graph libs/graph
+cd libs/graph
+git remote add upstream https://github.com/boostorg/graph
+```
+
+## Building and testing
+
+- Headers only: `./b2 headers` from boost root
+- Compiled components: `./b2` from `libs/graph`
+- All tests: `./b2` from `libs/graph/test` (takes ~10 min)
+- Single test: `./b2 cycle_canceling_test` from `libs/graph/test`
+- Different C++ standard: `./b2 cxxstd=20`
+- Different compiler: `./b2 toolset=clang`
+
+### Naming conventions
+
+BGL follows the standard Boost / STL conventions:
+
+| Kind | Style | Example |
+|---|---|---|
+| Functions, types, variables, files | `snake_case` | `dijkstra_visitor`, `add_edge`, `adjacency_list.hpp` |
+| Member functions / methods | `snake_case` (same as free functions) | `get_edge`, `out_edges` |
+| Private member variables | `m_` prefix + `snake_case` | `m_matrix`, `m_num_edges`, `m_property` |
+| Concept names | `PascalCase` | `IncidenceGraph`, `VertexListGraph` |
+| Template parameters | `PascalCase` | `template <class Graph, class WeightMap>` |
+| Tag-dispatch types | `snake_case` + `S` suffix | `vecS`, `directedS` |
+| Macros | `BOOST_GRAPH_` prefix, `SCREAMING_SNAKE_CASE` | `BOOST_GRAPH_DECLARE_EDGE_PROPERTY` |
+
+### Formatting
+
+Low-level formatting (braces, column width, spaces in angle brackets, etc.) is captured by the [`.clang-format`](.clang-format) file at the repo root (WebKit preset with BGL-specific overrides: Allman braces, 80-column limit, `Cpp03`). It is **not** enforced by CI, but contributors are encouraged to run `clang-format -i` on files they touch before opening a PR.
+
+## Using other Boost libraries
+
+When writing new code:
+
+- **Prefer `std::`** when the supported C++ standard has an equivalent. Use `std::function`, `std::shared_ptr`, `std::tuple` over their Boost counterparts. Exceptions are welcome with justification in the PR description, in particular Boost containers with no std equivalent in our standard window (e.g. `boost::unordered_flat_map`, `boost::bimap`, `boost::multi_index_container`).
+- **Avoid pulling in new heavy dependencies** (Spirit, property_tree, xpressive, etc.) without justification: BGL is gradually migrating away from heavy Boost dependencies. Open a discussion before adding one.
+- **Concept checks** (`boost::concept`) are encouraged for any new public template. New public APIs should respect the existing concept hierarchy. 
+- Track BGL's position in the Boost dependency DAG via [boostdep](https://github.com/boostorg/boostdep)'s hosted reports. The long-term goal is to reduce BGL's level over time:
+    - **[Module levels](https://pdimov.github.io/boostdep-report/master/module-levels.html#graph)** shows BGL's depth in the global DAG. A rising level means new transitive Boost dependencies have been pulled in.
+    - **[Per-library page](https://pdimov.github.io/boostdep-report/develop/graph.html)** shows BGL's direct deps and per-dep `#include` counts.
+
+## Boost macro usage
+
+BGL has accumulated a wide vocabulary of `BOOST_*` macros from its pre-C++14 days. The table below captures the current guidance for each one used in the codebase: **Keep** as-is, **Replace** with a language or std equivalent, or **Remove** along with the dead `#if defined(...)` branch the macro guards. When in doubt, follow the recommendation here or ask before introducing new uses.
+
+| Macro | Recommendation |
+|---|---|
+| `BOOST_ASSERT` | Keep, more useful and configurable than `assert` |
+| `BOOST_BORLANDC` | Remove |
+| `BOOST_CONCEPT_ASSERT` | Keep (pre C++20) |
+| `BOOST_CONCEPT_REQUIRES` | Keep (pre C++20) |
+| `BOOST_CONCEPT_USAGE` | Keep (pre C++20) |
+| `BOOST_DEDUCED_TYPENAME` | Remove |
+| `BOOST_FOREACH` | Replace with an appropriate algorithm or range-based `for` loop |
+| `BOOST_FWD_REF` | Replace with `T&&` |
+| `BOOST_JOIN` | Keep |
+| `BOOST_MPL_HAS_XXX_TRAIT_DEF` | Consider writing the same utility without dependency on MPL |

+| `BOOST_NO_CXX11_RVALUE_REFERENCES` | Remove |
+| `BOOST_NO_CXX11_SMART_PTR` | Remove |
+| `BOOST_NO_CXX17_STRUCTURED_BINDINGS` | Keep |
+| `BOOST_NO_MEMBER_TEMPLATE_FRIENDS` | Remove |
+| `BOOST_NO_SFINAE` | Remove |
+| `BOOST_NO_STDC_NAMESPACE` | Possibly keep |
+| `BOOST_NO_STD_ALLOCATOR` | Remove |
+| `BOOST_NO_STD_ITERATOR_TRAITS` | Remove |
+| `BOOST_NO_TEMPLATED_ITERATOR_CONSTRUCTORS` | Remove |
+| `BOOST_OVERRIDE` | Possibly remove |
+| `BOOST_PARAMETER_KEYWORD` | Keep |
+| `BOOST_PARAMETER_NAME` | Keep |
+| `BOOST_PP_CAT` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_COMMA_IF` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_DEC` | Use if Boost.PP can't be replaced with variadics |

+| `BOOST_PP_INC` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_LPAREN_IF` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_REPEAT` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_REPEAT_FROM_TO` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_RPAREN_IF` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_SEQ_ELEM` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_SUB` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PP_TUPLE_EAT` | Use if Boost.PP can't be replaced with variadics |
+| `BOOST_PREVENT_MACRO_SUBSTITUTION` | Keep |
+| `BOOST_SERIALIZATION_NVP` | Consider removing if you can eliminate the dependency on Boost.Serialization via `<boost/core/serialization.hpp>` |
+| `BOOST_SPIRIT_CLOSURE_LIMIT` | Keep |
+| `BOOST_SPIRIT_DEBUG` | Keep |
+| `BOOST_SPIRIT_DEBUG_RULE` | Keep |
+| `BOOST_STATIC_ASSERT` | Replace with `static_assert(..., msg)` |
+| `BOOST_STATIC_ASSERT_MSG` | Replace with `static_assert(..., msg)` |

+| `BOOST_SYMBOL_EXPORT` | Keep |
+| `BOOST_SYMBOL_IMPORT` | Keep |
+| `BOOST_SYMBOL_VISIBLE` | Keep |
+| `BOOST_TESTED_AT` | Keep |
+| `BOOST_THROW_EXCEPTION` | Keep |
+| `BOOST_TTI_HAS_MEMBER_FUNCTION` | Consider writing the same utility without dependency on TTI |
+| `BOOST_USING_STD_MAX` | Replace with `(std::max)(...)` |
+| `BOOST_USING_STD_MIN` | Replace with `(std::min)(...)` |
+| `BOOST_WORKAROUND` | Keep |
+
+When you mark a `BOOST_NO_*` flag as **Remove**, also delete the `#if defined(...)` block it gates — the alternate branch is always taken on the supported toolchains.
+
+## Pull request process
+
+- Fork, branch from `develop`, PR back to `develop`
+- One logical change per PR; rebase before requesting review
+- Tests required for new features and bug fixes
+- **Open (non-draft) PRs are assumed ready for review.** Use GitHub's Draft state while iterating, then mark the PR as *Ready for review* when you want maintainers to look at it.
+- A maintainer will review within ~2 weeks (see Maintainers below)
+- Squash on merge by default
+
+## Merge criteria
+
+Before a PR is merged, all of the following must hold:
+
+1. CI is green on the full matrix (gcc-14 + clang-19, C++14/17/20/23).
+2. New behavior has tests.
+3. Bug fixes have a regression test.
+4. Documentation under [doc/](doc/) is updated if the public API changed.
+5. No new compiler warnings on the supported toolchains.
+6. The PR is rebased on current `develop` with a clean commit history.
+7. The principal maintainer has approved.
+
+## Reporting bugs
+
+1. Search [existing issues](https://github.com/boostorg/graph/issues) first
+2. Note compiler, version, OS, Boost version
+3. Minimal reproducer on [Compiler Explorer](https://godbolt.org/z/37dPWd5bs)
+4. Expected Output versus Actual Output is explained.

-A generic interface for traversing graphs, using C++ templates.
+The Boost Graph Library (BGL) is a generic library that allows users to:

-The full documentation is available on [boost.org](http://www.boost.org/doc/libs/release/libs/graph/doc/index.html).
+1. Represent graph data using different structures (adjacency matrix, adjacency list, compressed sparse row, vectors of vectors, user-defined data structures).
+2. Attach user-defined data to vertices, edges, or the graph itself.
+3. Run a large number of algorithms on the graph.
+4. Inject user logic into algorithms using visitor hooks.

+## Algorithms

-The Boost Graph Library is located in `libs/graph/`.
+BGL ships dozens of graph algorithms: shortest paths (Dijkstra, Bellman-Ford, A*, Floyd-Warshall, Johnson), spanning trees (Kruskal, Prim), maximum flow (Edmonds-Karp, push-relabel, Boykov-Kolmogorov), traversal (BFS, DFS, topological sort), planarity testing, isomorphism, component decomposition, and more.

-Boost Graph Library is mostly made of headers but also contains some compiled components. Here are the build commands:
+See the [full algorithm reference](https://becheler.github.io/graph/graph/algorithms/overview.html) for the complete catalogue.

-    ./bootstrap.sh            <- compile b2
-    ./b2 headers              <- just installs headers
-    ./b2                      <- build compiled components
+## Help and feedback

-**Note:** The Boost Graph Library cannot currently be built outside of Boost itself.
+* **[GitHub Issues](https://github.com/boostorg/graph/issues)** for bug reports. Search before opening a new one.
+* **[GitHub Discussions](https://github.com/boostorg/graph/discussions)** for questions, design ideas, and general conversation about the library.
+* **[Boost mailing list](http://lists.boost.org/mailman/listinfo.cgi/boost-users)** for general Boost development. Use the `[graph]` tag in the subject line.
+* **CppLang Slack** for real-time chat. [Request an invite](https://cppalliance.org/slack/), then join the `#boost` channel.
+* **Direct contact with maintainers**: see [CONTRIBUTING.md#maintainers](CONTRIBUTING.md#maintainers).

-### Running tests ###
-First, make sure you are in `libs/graph/test`.
-You can either run all the 300+ tests listed in `Jamfile.v2` or run a single test:
+## Using BGL

-    ../../../b2                        <- run all tests
-    ../../../b2 cycle_canceling_test   <- single test
+Install Boost via your package manager:

-You can also check the [regression tests reports](http://beta.boost.org/development/tests/develop/developer/graph.html).
+| Manager | Command |
+|---|---|
+| [vcpkg](https://vcpkg.io) | `vcpkg install boost-graph` |
+| [Conan](https://conan.io) | `conan install --requires=boost/[*]` |
+| apt (Debian/Ubuntu) | `sudo apt install libboost-graph-dev` |
+| Homebrew (macOS) | `brew install boost` |
+
+Then wire it into CMake:
+
+```cmake
+find_package(Boost REQUIRED COMPONENTS graph)
+target_link_libraries(my_app PRIVATE Boost::graph)
+```
+
+Most of BGL is header-only. Linking `Boost::graph` is only required for the GraphViz and GraphML parsers.

+# Security Policy
+
+Boost.Graph is a header-only C++ template library. Most issues that look
+like security problems are caused by misuse of the API, undefined behavior
+in caller code, or violating a documented precondition. Those should be
+filed as regular GitHub issues.
+

-<H1>AStar Heuristic Concept</H1>
-
-This concept defines the interface for the heuristic function of an A*
-search, which is responsible for estimating the remaining cost from
-some vertex to a goal.  The user can create a class that matches this
-interface, and then pass objects of the class into <a
-href="./astar_search.html"><tt>astar_search()</tt></a> to guide the
-order of vertex examination of the search.  The heuristic instance
-must incorporate any necessary information about goal vertices in the
-graph.
-
-For further discussion of the use of heuristics in an A* search, see
-the documentation of <a
-href="./astar_search.html">astar_search()</a>.

-<h1>AddEdgeVisitor Concept</h1>
-
-The AddEdgeVisitor concept exists to allow for some indirection in algorithms
-that modify graphs by adding edges. In such algorithms, it may be convenient
-to perform additional operations (such as updating an edge index map) at
-points in the algorithm where an edge addition occurs. Replacing calls to
-to <tt>add_edge</tt> with calls to <tt>AddEdgeVisitor::visit_vertex_pair</tt>
-allows for such operations to be defined independently from the algorithm.

-
-Two models of this concept are defined in the file
-<a href="../../../boost/graph/planar_detail/add_edge_visitors.hpp">
-<tt>add_edge_visitors.hpp</tt></a>:
-
-<ul>
-<li><tt>default_add_edge_visitor</tt>: The constructor of this class takes
-no arguments.<tt>visit_vertex_pair(u, v, g)</tt> is just a dispatch to
-<tt>add_edge(u, v, g)</tt>.
-<li><tt>edge_index_update_visitor</tt>: The constructor of this class takes
-two arguments: the first, an EdgeIndexMap,
-is a <a href="../../property_map/doc/ReadWritePropertyMap.html">
-ReadWritePropertyMap</a> that maps each edge in the associated graph
-<tt>g</tt> to a distinct integer in the range <tt>[0, num_edges(g))</tt>.
-The second argument is the number of edges in the underlying graph, which
-serves as the "next available index" counter within the visitor.
-For example, in the case the graph used has an initialized interior
-edge index, the <tt>edge_index_update_visitor</tt> constructor should be
-called with <tt>get(edge_index, g)</tt> as the edge index and
-<tt>num_edges(g)</tt> as the next available index. When
-<tt>visit_vertex_pair(u, v, g)</tt> is called, the
-<tt>edge_index_update_visitor</tt> will add the edge <i>(u,v)</i> to the graph
-and update the edge index for the newly created edge.

-The AdjacencyGraph concept provides an interface for efficient access

-to the <a href="./IncidenceGraph.html">IncidenceGraph</a> concept (the
-target of an out-edge is an adjacent vertex). Both concepts are
-provided because in some contexts there is only concern for the
-vertices, whereas in other contexts the edges are also important.

-
-<h3>Design Rationale</h3>
-
-The AdjacencyGraph concept is somewhat frivolous since <a
-href="./IncidenceGraph.html">IncidenceGraph</a> really covers the same
-functionality (and more).  The AdjacencyGraph concept exists because
-there are situations when <tt>adjacent_vertices()</tt> is more
-convenient to use than <tt>out_edges()</tt>. If you are constructing a
-graph class and do not want to put in the extra work of creating an
-adjacency iterator, have no fear. There is an adaptor class named <a
-href="./adjacency_iterator.html"> <tt>adjacency_iterator</tt></a> that
-you can use to create an adjacency iterator out of an out-edge
-iterator.
-
-<h3>Notes</h3>
-
-<a name="1">[1]</a>  The case of a
-<I>multigraph</I> (where multiple edges can connect the same two
-vertices) brings up an issue as to whether the iterators returned by
-the <TT>adjacent_vertices()</TT> function access a range that
-includes each adjacent vertex once, or whether it should match the
-behavior of the <TT>out_edges()</TT> function, and access a
-range that may include an adjacent vertex more than once. For now the
-behavior is defined to match that of <TT>out_edges()</TT>,
-though this decision may need to be reviewed in light of more
-experience with graph algorithm implementations.

-<h3>Buffer Concept</h3>
-
-A Buffer is something in which items can be put and removed.
-The Buffer <i>concept</i> has very few requirements. It does
-not require any particular ordering of how the items are stored or in
-what order they will appear when removed, however, there is typically
-some sort of ordering policy.
-
-<h3>Notation</h3>
-
-<table>
-<tr> <td> <tt>B</tt> </td>  <td> is a type that models Buffer.       </td></tr>
-<tr> <td> <tt>T</tt> </td>  <td> is the value type of <tt>B</tt>. </td></tr>
-<tr> <td> <tt>t</tt> </td>  <td> is an object of type <tt>T</tt>. </td></tr>

+# Contributing to the Boost.Graph documentation
+
+The docs are built with [Antora](https://antora.org) from AsciiDoc
+sources under `doc/modules/ROOT/`.
+
+## Layout
+
+| Where | What |
+|---|---|
+| `doc/modules/ROOT/pages/`     | All `.adoc` pages (organized by topic) |
+| `doc/modules/ROOT/examples/`  | One `.cpp` per page; the build script captures stdout into a sibling `.txt` |
+| `doc/modules/ROOT/nav.adoc`   | Left-side navigation tree |
+| `doc/templates/`              | Starter templates: `algorithm.adoc`, `generator.adoc`, `graph_class.adoc` — copy and fill in |
+| `doc/playbook.yml`            | Antora playbook (UI bundle, content sources) |
+| `doc/modules/ROOT/examples/Jamfile` | b2 rules that compile every example and snapshot its stdout into a sibling `.txt` |
+| `doc/build_example_outputs.sh`| g++-only fallback that does the same thing as the Jamfile, for contributors without a `boost-root` checkout |
+
+## Adding a new page
+
+1. Pick a template in `doc/templates/` and copy it into the right
+   `pages/` subdirectory.
+2. Replace the placeholders (title, signatures, parameter table). Keep
+   the section order from the template so the page is consistent with
+   the rest.
+3. Add an `.cpp` example under `modules/ROOT/examples/` at the path
+   the page's `include::example$…[]` directive points to.
+4. Add an `xref:` line to `doc/modules/ROOT/nav.adoc`.
+
+## Building locally
+
+The example outputs are generated by b2 (the standard Boost build
+system). From a `boost-root` layout:
+
+```sh
+# 1) Compile every example and snapshot its stdout into a sibling .txt.
+b2 libs/graph/doc/modules/ROOT/examples
+
+# 2) Build the static site.
+cd libs/graph
+npx antora doc/playbook.yml
+
+# 3) Open the result.
+open doc/build/site/index.html       # macOS
+xdg-open doc/build/site/index.html   # Linux
+```
+
+CI runs the same commands on every push.
+
+### Quick fallback (no boost-root required)
+
+For doc-only contributors who only want to fix typos and don't have a
+boost-root checkout, a shell-script equivalent is provided:
+
+```sh
+BOOST_INCLUDE=/path/to/boost/include \
+BOOST_LIB=/path/to/boost/lib \
+bash doc/build_example_outputs.sh
+```
+
+Functionally equivalent to step 1 above; uses g++ directly instead of
+b2. `BOOST_LIB` is only needed for the three link-required examples
+(`io/graphml.cpp`, `io/graphviz.cpp`,
+`algorithms/isomorphism/isomorphism.cpp`).
+
+## Conventions
+
+- **Examples first.** `== Example` (with `*Expected output:*` block)
+  goes immediately after `*Defined in:*` so readers see working code
+  before signatures.
+- **Bold metadata.** `*Complexity:*`, `*Defined in:*`,
+  `*Expected output:*` are bold.
+- **Output blocks** use `[,text]\n----` (same listing-block wrapper as
+  the code above) and pull from the `.txt` sidecar via
+  `include::example$…[]`, so the documentation can never drift from the
+  code and the two blocks align vertically on the page.
+- **Heading levels:** `==` for top-level sections; `===` only for
+  numbered overloads or grouped variants. The `'''` thematic break
+  appears only before a `===`, never before a `==`.
+- **Bundled properties** preferred over interior tag properties in
+  examples, unless the algorithm requires the tag.

-<H1>EventVisitorList Concept</H1>
-
-An EventVisitorList is either an <a
-href="./EventVisitor.html">EventVisitor</a>, or a list of
-EventVisitors combined using <tt>std::pair</tt>. Each graph algorithm
-defines visitor adaptors that convert an EventVisitorList into the
-particular kind of visitor needed by the algorithm.
-
-In the following example we will show how to combine event visitors
-into a list using <tt>std::pair</tt> and how to use an algorithm's
-visitor adaptor class.
-
-<p>
-Suppose we would like to print out the parenthesis
-structure of the discover/finish times of vertices in a <a
-href="./graph_theory_review.html#sec:dfs-algorithm">depth-first
-search</a>. We can use the BGL algorithm <a
-href="./depth_first_search.html"><tt>depth_first_search()</tt></a> and
-two event visitors to accomplish this. The complete source code for
-the following example is in <a href="../example/dfs_parenthesis.cpp">
-<tt>examples/dfs_parenthesis.cpp</tt></a>. First we define the two
-event visitors. We use <tt>on_discover_vertex</tt> and
-<tt>on_finish_vertex</tt> as the event points, selected from the list
-of event points specified in <a
-href="./DFSVisitor.html">DFSVisitor</a>.
-
-<pre>
-struct open_paren : public base_visitor&lt;open_paren&gt; {
-  typedef on_discover_vertex event_filter;
-  template &lt;class Vertex, class Graph&gt;
-  void operator()(Vertex v, Graph& G) {
-    std::cout &lt;&lt; "(" &lt;&lt; v;
-  }
-};
-struct close_paren : public base_visitor&lt;close_paren&gt; {
-  typedef on_finish_vertex event_filter;
-  template &lt;class Vertex, class Graph&gt;
-  void operator()(Vertex v, Graph& G) {
-    std::cout &lt;&lt; v &lt;&lt; ")";
-  }
-};
-</pre>
-
-Next we create two event visitor objects and make an EventVisitorList
-out of them using a <tt>std::pair</tt> which created by
-<tt>std::make_pair</tt>.
-
-<pre>
-std::make_pair(open_paren(), close_paren())
-</pre>
-
-Next we want to pass this list into <tt>depth_first_search()</tt>, but
-<tt>depth_first_search()</tt> is expecting a <a

-IteratorConstructibleGraph
-</H1>
-
-The IteratorConstructibleGraph concept describes the interface for
-graph types that can be constructed using a kind of edge iterator. The
-edge iterator can be any <a
-href="http://www.boost.org/sgi/stl/InputIterator.html">InputIterator</a>
-that dereferences to a pair of integers <i>(i,j)</i>, which represent
-an edge that should be in the graph. The two integers <i>i</i> and
-<i>j</i> represent vertices where <i>0 <= i < |V|</i> and <i>0 <= j <
-|V|</i>.  The edge iterator's value type should be
-<tt>std::pair&lt;T,T&gt;</tt> (or at least be a structure that has
-members <tt>first</tt> and <tt>second</tt>) and the value type
-<tt>T</tt> of the pair must be convertible to the
-<tt>vertices_size_type</tt> of the graph (an integer).
-
-There are two valid expressions required by this concept, both of
-which are constructors. The first creates a graph object from a
-first/last iterator range. The second constructor also takes a
-first/last iterator range and in addition requires the number of
-vertices and number of edges. For some graph and edge iterator types
-the second constructor can be more efficient than the first.
-
-<h3>Example</h3>
-
-The following exampe creates two graph objects from an array of edges
-(vertex pairs). The type <tt>Edge*</tt> satisfies the requirements for
-an <a
-href="http://www.boost.org/sgi/stl/InputIterator.html">InputIterator</a>
-and can therefore be used to construct a graph.

-      Edge(1, 2), Edge(1,5), Edge(1,3),
-      Edge(2, 4), Edge(2,5),
-      Edge(3, 2),
-      Edge(4, 3), Edge(4,1),
-      Edge(5, 4) };
-  Edge* first = edge_array,
-    last = edge_array + sizeof(edge_array)/sizeof(Edge);

-A <i>Monoid</i> is a concept that describes a simple kind of algebraic

-monoid consists of a function object that implements the binary
-operation, a set of objects that represent the elements of <i>S</i>,
-and an object that represents the identity element.

-<h1>Planar Embedding Concept</h1>
-
-
-A planar embedding is an important intermediate representation of a drawing
-of a planar graph. Instead of specifying the absolute positions of the vertices
-and edges in the plane, a planar embedding specifies their positions relative
-to one another. A planar embedding consists of a sequence, for each vertex in
-the graph, of all of the edges incident on that vertex in the order in which
-they are to be drawn around that vertex.
-<p>
-A planar embedding is a refinement of
-<a href="../../property_map/doc/LvaluePropertyMap.html">LValuePropertyMap</a> that
-places additional restrictions the <tt>value_type</tt> used in the property
-map.

-<pre>
-#include &lt;boost/property_map/property_map.hpp&gt;
-#include &lt;vector&gt;
-
-...
-
-// Assume a graph type "Graph" defined somewhere above and
-// an instance of Graph in a variable g.
-
-// A typedef for the storage - a vector of vectors of edge descriptors
-typedef
-    std::vector&lt; std::vector&lt; graph_traits&lt;Graph&gt;::edge_descriptor &gt; &gt;
-    planar_embedding_storage_t;
-
-// A typedef for the iterator property map, assuming the graph has
-// an interior vertex index map
-typedef
-    boost::iterator_property_map&lt; planar_embedding_storage_t::iterator,
-                                  property_map&lt;Graph, vertex_index_t&gt;::type
-                                &gt;
-    planar_embedding_t;
-
-// Create an instance of the storage and the property map
-planar_embedding_storage_t planar_embedding_storage(num_vertices(g));
-planar_embedding_t planar_embedding(planar_embedding_storage.begin(),
-                                    get(vertex_index, g)
-                                    );

-A PropertyGraph is a graph that has some property associated with each

-<h2><a name="concept:UpdatableQueue">UpdatableQueue</a></h2>
-
-<p>An <i>UpdatableQueue</i> is a refinement of the <a href="./Buffer.html">Buffer</a> concept that additionally requires that the Buffer be updatable.
-
-<p>Implicit in the definition is an ordering of values. Though access to the order is not required, types that model UpdatableQueue must document how an object of the type orders values so that a program may change the position of a given value in the ordering. For example, an UpdatableQueue may choose to order values by using a property map, and a value <tt>v1</tt> is considered less than a value <tt>v2</tt> if <tt><nobr>get(pm, v1) &lt; get(pm, v2)</nobr></tt>. A program can update the properties of values, thus changing the order of values in the UpdatableQueue, and notify the UpdatableQueue of the specific values that have a different position in the ordering by calling the <tt>update</tt> member of the UpdatableQueue on each.
-
-<p>A program that modifies the order must notify the UpdatableQueue of values that may have different positions in the ordering since they were inserted or last updated.

-<h2><a name="concept:UpdatablePriorityQueue">UpdatablePriorityQueue</a></h2>
-<p>An <i>UpdatablePriorityQueue</i> is a slight refinement of <a href="#concept%3AUpdatableQueue">UpdatableQueue</a>
-that imposes the requirement that a program may not increase the position of a value that is held in the queue. That is,
-if a value <tt>v</tt> had position <i>n</i> in the ordering, a program may update the position of <tt>v</tt> only to 0, 1, ..., <i>n</i>&nbsp;-&nbsp;1, or <i>n</i>, where 0 is the top of the queue.
-
-<p>The behavior when a program attempts to increase a value's position in the ordering is undefined.

-
-One issue in the design of this concept is whether to include the
-refinement from the <a href="./IncidenceGraph.html">IncidenceGraph</a>
-and <a href="./AdjacencyGraph.html">AdjacencyGraph</a> concepts.  The
-ability to traverse the vertices of a graph is orthogonal to
-traversing out-edges, so it would make sense to have a VertexListGraph
-concept that only includes vertex traversal. However, such a concept
-would no longer really be a graph, but would just be a set, and the
-STL already has concepts for dealing with such things. However, there
-are many BGL algorithms that need to traverse the vertices and
-out-edges of a graph, so for convenience a concept is needed that
-groups these requirements together, hence the VertexListGraph concept.

-<h1>Adjacency Iterator Adaptor</h1>
-
-Defined in header
-<a href="../../../boost/graph/adjacency_iterator.hpp">boost/graph/adjacency_iterator.hpp</a>
-
-<p>
-The adjacency iterator adaptor transforms an
-<tt>out_edge_iterator</tt> into an adjacency iterator. That is, it
-takes an iterator that traverses over edges, and creates an iterator
-that traverses over the <b><i>target</i></b> vertices of those edges.
-With this adaptor it is trivial to take a graph type that models <a
-href="IncidenceGraph.html">Incidence Graph</a> and add the
-capabilities required of <a href="AdjacencyGraph.html">Adjacency
-Graph</a>.
-
-
-<h2>Synopsis</h2>
-
-<pre>
-namespace boost {
-  template &lt;class Graph, class VertexDescriptor, class OutEdgeIter&gt;
-  class adjacency_iterator_generator {
-  public:
-    typedef <a href="../../iterator/doc/iterator_adaptor.html">iterator_adaptor</a>&lt;...&gt; type;
-  };
-}
-</pre>
-
-<hr>
-
-<h3>Example</h3>
-
-<p>
-The following is an example of how to use the
-<tt>adjacency_iterator_generator</tt> class.
-
-<p>
-<PRE>
-#include &lt;boost/graph/adjacency_iterator.hpp&gt;
-
-class my_graph {
-  // ...
-  typedef ... out_edge_iterator;
-  typedef ... vertex_descriptor;
-  typedef boost::adjacency_iterator_generator&lt;my_graph, vertex_descriptor, out_edge_iterator&gt;::type adjacency_iterator;
-  // ...

-<h3>Members</h3>
-
-The adjacency iterator type implements the member functions and

-This class provides an alternate method for accessing some of the
-associated types of the <tt>adjacency_list</tt> class. The main reason
-for this class is that sometimes one would like to create graph
-properties whose values are vertex or edge descriptors. If you try to
-use <tt>graph_traits</tt> for this you will run into a problem with
-mutually recursive types. To get around this problem, the
-<tt>adjacency_list_traits</tt> class is provided, which gives the user
-access to the vertex and edge descriptor types without requiring the
-user to provide the property types for the graph.

-The <tt>adjacency_matrix</tt> class implements the BGL graph interface
-using the traditional adjacency matrix storage format. For a graph
-with <i>V</i> vertices, a <i>V x V</i> matrix is used, where each
-element <i>a<sub>ij</sub></i> is a boolean flag that says whether
-there is an edge from vertex <i>i</i> to vertex <i>j</i>. <a
-href="#fig:adj-matrix-graph">Figure 1</a> shows the adjacency matrix
-representation of a graph.

-
-The advantage of this matrix format over the adjacency list is that
-edge insertion and removal is constant time.  There are several
-disadvantages. The first is that the amount of memory used is
-<i>O(V<sup>2</sup>)</i> instead of <i>O(V + E)</i> (where <i>E</i> is
-the number of edges). The second is that operations that traverse all
-the out-edges of each vertex (such as breadth-first search) run in
-<i>O(V<sup>2</sup>)</i> time instead of <i>O(V + E)</i> time for the
-adjacency list. In short, it is better to use the
-<tt>adjacency_matrix</tt> for dense graphs (where <i>E</i> is close to
-<i>V<sup>2</sup></i>) and it is better to use <a
-href="adjacency_list.html"><tt>adjacency_list</tt></a> for sparse
-graphs (where <i>E</i> is much smaller than <i>V<sup>2</sup></i>).
-
-The <tt>adjacency_matrix</tt> class extends the traditional
-data-structure by allowing objects to be attached to vertices and
-edges using the same property template parameters supported by <a
-href="adjacency_list.html"><tt>adjacency_list</tt></a>. These may be
-<a href="bundles.html">bundled properties</a> or standard (backward-compatible)
-<a
-href="using_adjacency_list.html#sec:adjacency-list-properties">interior
-properties</a>. The types of all property values must be
-Copy Constructible, Assignable and Default Constructible.
-
-In the case of an undirected graph, the
-<tt>adjacency_matrix</tt>. class does not use a full <i>V x V</i>
-matrix but instead uses a lower triangle (the diagonal and below)
-since the matrix for an undirected graph is symmetric. This reduces
-the storage to <i>(V<sup>2</sup>)/2</i>.  <a

-matrix representation of an undirected graph.

-<P>
-This algorithm implements a heuristic search on a weighted, directed
-or undirected graph for the case where all edge weights are
-non-negative.
-</P>
-
-<P>
-The A* algorithm is a <i>heuristic graph search algorithm</i>: an A*
-search is "guided" by a <i>heuristic function</i>.  A heuristic
-function <i>h(v)</i> is one which estimates the cost from a non-goal
-state (<i>v</i>) in the graph to some goal state, <i>g</i>.
-Intuitively, A* follows paths (through the graph) to the goal that are
-estimated by the heuristic function to be the best paths.  Unlike
-best-first search, A* takes into account the known cost from the start
-of the search to <i>v</i>; the paths A* takes are guided by a function
-<i>f(v) = g(v) + h(v)</i>, where <i>h(v)</i> is the heuristic
-function, and <i>g(v)</i> (sometimes denoted <i>c(s, v)</i>) is the
-known cost from the start to <i>v</i>.  Clearly, the efficiency of A*
-is highly dependent on the heuristic function with which it is used.
-</P>
-
-<P>
-The A* algorithm is very similar to Dijkstra's Shortest Paths
-algorithm.  This implementation finds all the shortest paths from the
-start vertex to every other vertex by creating a search tree,
-examining vertices according to their remaining cost to some goal, as
-estimated by a heuristic function.  Most commonly, A* is used to find
-some specific goal vertex or vertices in a graph, after which the
-search is terminated.
-</P>
-
-<P>
-A* is particularly useful for searching <i>implicit</i> graphs.
-Implicit graphs are graphs that are not completely known at the
-beginning of the search.  Upon visiting a vertex, its neighbors are
-"generated" and added to the search.  Implicit graphs are particularly
-useful for searching large state spaces -- in game-playing scenarios
-(e.g. chess), for example -- in which it may not be possible to store
-the entire graph.  Implicit searches can be performed with this
-implementation of A* by creating special visitors that generate
-neighbors of newly-expanded vertices.  Please note that
-<tt>astar_search_no_init()</tt> or <tt>astar_search_no_init_tree()</tt> must be
-used for implicit graphs; the basic
-<tt>astar_search()</tt> function requires a graph that models
-the <a href="VertexListGraph.html">Vertex List Graph</a> concept.  Both
-versions
-also require the graph type to model the <a
-href="IncidenceGraph.html">Incidence Graph</a> concept.
-</P>
-
-<P>
-For the non-tree versions of the algorithm,
-this implementation of A* is based on an OPEN/CLOSED list formulation.
-Vertices on the OPEN list have been ``discovered''
-by the algorithm, but not ``expanded'' (we have not discovered their
-adjacent vertices).  Vertices on the CLOSED list have been completely
-examined by our search (we have expanded them and added their children
-to the OPEN list).  Vertices that are on neither list have not been
-encountered in any context so far in our search.  A major advantage of
-this formulation of the A* algorithm over other approaches is that it
-avoids ``cycles'' in the state space; the search will not become
-trapped by loops in the graph.  The OPEN/CLOSED lists are implemented
-using BGL's vertex coloring mechanisms.  Vertices in OPEN are colored
-gray, vertices in CLOSED are colored black, and undiscovered vertices
-are colored white.  For the versions of the algorithm whose names end in
-<tt>_tree</tt>, all vertices are assumed to always be white, leading to
-checking for repeated vertices being done using the distance map.  If a dummy
-value is used for the distance map and the graph contains cycles, the algorithm
-will probably enter an infinite loop.
-</P>
-
-<P>
-The criteria for expanding a vertex on the OPEN list is that it has
-the lowest <i>f(v) = g(v) + h(v)</i> value of all vertices on OPEN.
-Cost information about vertices is stored in a property map.
-</P>
-
-<P>
-The following is the pseudocode for the A* heuristic search algorithm.
-In the pseudocode, <i>h</i> is the heuristic function, <i>w</i> is the
-edge weight, <i>d</i> is the distance of a vertex from <i>s</i>, and
-<i>Q</i> is a priority queue, sorted by <i>f</i>, the estimated cost
-to the goal of the path through a vertex.  <i>p</i> is a predecessor
-map.  The visitor event points for the algorithm are indicated by the
-labels on the right.

-<h2>Description</h2>
-<p>This algorithm implements graph clustering based on edge
-betweenness centrality. It is an iterative algorithm, where in each
-step it computes the edge betweenness centrality (via <a href=
-"betweenness_centrality.html">brandes_betweenness_centrality</a>) and
-removes the edge with the maximum betweenness centrality. The
-<tt class="computeroutput">done</tt> function object determines
-when the algorithm terminates (the edge found when the algorithm
-terminates will not be removed).</p>
-
-<h2>Parameters</h2>
-IN: <tt>const Graph&amp; g</tt>
-<blockquote>
-  The graph object on which the algorithm will be applied.  The type
-  <tt>Graph</tt> must be a model of <a
-  href="VertexListGraph.html">Vertex List Graph</a> and <a
-  href="IncidenceGraph.html">Incidence Graph</a>. When an edge
-  centrality map is supplied, it must also model <a
-  href="EdgeListGraph.html">Edge List Graph</a> and <a
-  href="MutableGraph.html">MutableGraph</a>.<br>
-
-<b>Python</b>: The parameter is named <tt>graph</tt>.
-</blockquote>
-
-IN: <tt>Done done</tt>
-<blockquote>
-The function object that indicates termination of the algorithm.
-It must be a ternary function object thats accepts the maximum
-centrality, the descriptor of the edge that will be removed, and
-the graph <tt class="computeroutput">g</tt>.<br>
-<b>Python</b>: Any callable Python object will suffice.
-</blockquote>
-
-OUT/UTIL: <tt>EdgeCentralityMap edge_centrality_map</tt>
-<blockquote>
-  This property map is used to accumulate the betweenness centrality
-  of each edge, and is a secondary form of output for the
-  algorithm. The type <tt>EdgeCentralityMap</tt> must be a model of <a
-  href="../../property_map/doc/ReadWritePropertyMap.html">Read/Write
-  Property Map</a>, with the graph's edge descriptor type as its key
-  type. The value type of this property map should be the same as the
-  value type of the <tt>CentralityMap</tt> property map.<br>
-
-  <b>Default:</b> a <tt>dummy_property_map</tt>, which requires no
-  work to compute and returns no answer.<br>
-  <b>Python</b>: The color map must be a <tt>edge_double_map</tt> for
-  the graph.<br>
-  <b>Python default</b>: <tt>graph.get_edge_double_map("centrality")</tt>
-</blockquote>
-
-IN: <tt>VertexIndexMap vertex_index</tt>
-<blockquote>
-  This maps each vertex to an integer in the range <tt>[0,
-    num_vertices(g))</tt>. This is necessary for efficient updates of the
-  heap data structure when an edge is relaxed.  The type
-  <tt>VertexIndexMap</tt> must be a model of
-  <a href="../../property_map/doc/ReadablePropertyMap.html">Readable Property Map</a>. The value type of the map must be an
-  integer type. The vertex descriptor type of the graph needs to be
-  usable as the key type of the map.<br>
-  <b>Default:</b> <tt>get(vertex_index, g)</tt>.
-    Note: if you use this default, make sure your graph has
-    an internal <tt>vertex_index</tt> property. For example,
-    <tt>adjacency_list</tt> with <tt>VertexList=listS</tt> does
-    not have an internal <tt>vertex_index</tt> property.<br>
-  <b>Python</b>: Unsupported parameter.

-HREF="bibliography.html#ford62:_flows">11</A>,<A
-HREF="bibliography.html#lawler76:_comb_opt">20</A>,<A
-HREF="bibliography.html#clr90">8</A>] solves the single-source
-shortest paths problem for a graph with both positive and negative
-edge weights. For the definition of the shortest paths problem see
-Section <A
-HREF="./graph_theory_review.html#sec:shortest-paths-algorithms">Shortest-Paths
-Algorithms</A>.
-If you only need to solve the shortest paths problem for positive edge
-weights, Dijkstra's algorithm provides a more efficient
-alternative. If all the edge weights are all equal to one then breadth-first
-search provides an even more efficient alternative.
-</p>
-
-<p>
-Before calling the <tt>bellman_ford_shortest_paths()</tt> function,
-the user must assign the source vertex a distance of zero and all
-other vertices a distance of infinity <i>unless</i> you are providing
-a starting vertex. The Bellman-Ford algorithm
-proceeds by looping through all of the edges in the graph, applying
-the relaxation operation to each edge. In the following pseudo-code,
-<i>v</i> is a vertex adjacent to <i>u</i>, <i>w</i> maps edges to
-their weight, and <i>d</i> is a distance map that records the length
-of the shortest path to each vertex seen so far. <i>p</i> is a
-predecessor map which records the parent of each vertex, which will
-ultimately be the parent in the shortest paths tree

-There are two main options for obtaining output from the
-<tt>bellman_ford_shortest_paths()</tt> function. If the user provides
-a distance property map through the <tt>distance_map()</tt> parameter
-then the shortest distance from the source vertex to every other
-vertex in the graph will be recorded in the distance map (provided the
-function returns <tt>true</tt>). The second option is recording the
-shortest paths tree in the <tt>predecessor_map()</tt>. For each vertex
-<i>u in V</i>, <i>p[u]</i> will be the predecessor of <i>u</i> in the
-shortest paths tree (unless <i>p[u] = u</i>, in which case <i>u</i> is
-either the source vertex or a vertex unreachable from the source).  In
-addition to these two options, the user can provide her own
-custom-made visitor that can take actions at any of the
-algorithm's event points.

-<h3>Notes</h3>
-
-<p><a name="1">[1]</a>
-  Since the visitor parameter is passed by value, if your visitor
-  contains state then any changes to the state during the algorithm
-  will be made to a copy of the visitor object, not the visitor object
-  passed in. Therefore you may want the visitor to hold this state by
-  pointer or reference.

-<p>This algorithm&nbsp;[<a href="bibliography.html#brandes01">54</a>]

-href="bibliography.html#freeman77">55</a>,<a
-href="bibliography.html#anthonisse71">56</a>] of each vertex or each
-edge in the graph. The betweenness centrality of a vertex <em>v</em>
-is defined by
-
-<p><img src="figs/betweenness_centrality.gif">,
-
-<p>where <img src="figs/sigma_st.gif"> is the number of shortest paths from

-<p>The edge betweenness centrality indicates for each edge the
-betweenness centrality that was contributed to the target(s) of the
-edge (plural for undirected graphs). Similar to (vertex) betweenness
-centrality, edge betweenness centrality can be used to determine the
-edges through which most shortest paths must pass. A single invocation

-both).</p>
-
-<p>This algorithm can operate either on weighted graphs (if a suitable
-edge weight map is supplied) or unweighted graphs (if no edge weight
-map is supplied). The result is the absolute betweenness centrality;
-to convert to the relative betweenness centrality, which scales each
-absolute centrality by <img src="figs/rel_betweenness_centrality.gif">
-(where <em>n</em> is the number of vertices in the graph), use
-<tt>relative_betweenness_centrality</tt>. Given the relative
-betweenness centrality, one can compute the <em>central point
-dominance</em>&nbsp;[<a href="bibliography.html#freeman77">55</a>], which is a measure of the maximum "betweenness" of any

-<p>
-Many of the Boost.Graph algorithms have a long list of parameters,
-most of which have default values. This causes several problems.
-First, C++ does not provide a mechanism for handling default
-parameters of template functions. However, this can be overcome by
-creating multiply version of an algorithm with different numbers of
-parameters with each version providing defaults for some subset of
-the parameters. This is the approach used in previous versions of
-Boost.Graph. This solution is still unsatisfactory for several
-reasons:
-
-<ul>
-  <li>The defaults for parameters can only been used in a particular
-  order. If the ordering of the defaults does not fit the users situation
-  he or she has to resort to providing all the parameters.
-
-  <li>Since the list of parameters is long, it is easy to forget
-   the ordering.
-</ul>
-
-<p>
-A better solution is provided by <tt>bgl_named_params</tt>. This class
-allows users to provide parameters is any order, and matches
-arguments to parameters based on parameter names.
-
-<p>
-The following code shows an example of calling
-<tt>bellman_ford_shortest_paths</tt> using the named parameter
-technique. Each of the arguments is passed to a function whose name
-indicates which parameter the argument is for. Each of the named
-parameters is separated by a <b>period</b>, not a comma.
-
-<pre>
-  bool r = boost::bellman_ford_shortest_paths(g, int(N),
-     boost::weight_map(weight).
-     distance_map(&amp;distance[0]).
-     predecessor_map(&amp;parent[0]));
-</pre>
-
-<p>The order in which the arguments are provided does not matter as
-long as they are matched with the correct parameter function.  Here is
-an call to <tt>bellman_ford_shortest_paths</tt> that is equivalent to
-the one above.
-
-<pre>
-  bool r = boost::bellman_ford_shortest_paths(g, int(N),
-     boost::predecessor_map(&amp;parent[0]).
-     distance_map(&amp;distance[0]).
-     weight_map(weight));
-</pre>
-
-<p>Typically the user never needs to deal with the
-<tt>bgl_named_params</tt> class directly, since there are functions
-like <tt>boost::weight_map</tt> that create an instance of
-<tt>bgl_named_params</tt>.

-A connected graph is <i>biconnected</i> if the removal of any single
-vertex (and all edges incident on that vertex) can not disconnect the
-graph. More generally, the biconnected components of a graph are the
-maximal subsets of vertices such that the removal of a vertex from a
-particular component will not disconnect the component. Unlike
-connected components, vertices may belong to multiple biconnected
-components: those vertices that belong to more than one biconnected
-component are called <em>articulation points</em> or, equivalently,
-<em>cut vertices</em>. Articulation points are vertices whose removal
-would increase the number of connected components in the graph. Thus,
-a graph without articulation points is biconnected. The following
-figure illustrates the articulation points and biconnected components
-of a small graph:
-
-<p><center><img src="figs/biconnected.png"></center>
-
-<p>Vertices can be present in multiple biconnected components, but each
-edge can only be contained in a single biconnected component. The
-output of the <tt>biconnected_components</tt> algorithm records the
-biconnected component number of each edge in the property map
-<tt>comp</tt>. Articulation points will be emitted to the (optional)
-output iterator argument to <tt>biconnected_components</tt>, or can be
-computed without the use of a biconnected component number map via
-<tt>articulation_points</tt>. These functions return the number of
-biconnected components, the articulation point output iterator, or a
-pair of these quantities, depending on what information was
-recorded.
-
-<p>The algorithm implemented is due to Tarjan [<a href="bibliography.html#tarjan72:dfs_and_linear_algo">41</a>].

-\title{An Implementation of Biconnected Components}

-\section{Introduction}
-
-This paper documents the implementation of the
-\code{biconnected\_components()} function of the Boost Graph
-Library. The function was implemented by Jeremy Siek.
-
-The algorithm used to implement the \code{biconnected\_components()}
-function is the one based on depth-first search described
-by Tarjan~\cite{tarjan72:dfs_and_linear_algo}.
-
-An undirected graph $G = (V,E)$ is \emph{biconnected} if for each
-triple of distinct vertices $v, w, a \in V$ there is a path $p : v
-\Path w$ such that $a$ is not on the path $p$.  An \emph{articulation
-point} of $G = (V,E)$ is a vertex $a \in V$ where there are two other
-distinct vertices $v,w \in V$ such that $a$ is on any path $p:v \Path
-w$ and there is at least one such path. If $a$ were to be removed from
-$G$, then $v$ and $w$ would no longer be reachable from each other.
-So articulation points act as bridges between biconnected components;
-the only path from one biconnected component to another is through an
-articulation point.
-
-The algorithm finds articulation points based on information provided
-by depth-first search. During a DFS, we label each vertex $v \in G$
-with its discover time, denoted $d[v]$.  During the DFS we also
-compute the $lowpt(v)$, which is the smallest (in terms of discover
-time) vertex reachable from $v$ by traversing zero or more DFS-tree
-edges followed by at most one back edge. Tree edges and back edges can
-be identified based on discover time because for tree edge $(u,v)$ we
-have $d[u] < d[v]$ and for back edge $(u,v)$ we have $d[u] >
-d[v]$. The $lowpt(v)$ is computed for $v$ by taking the minimum
-$lowpt$ of the vertices to which $v$ is adjacent.  The $lowpt(v)$ is
-computed after the recursive DFS call so the $lowpt$ has already been
-computed for the adjacent vertices by the time $lowpt(v)$ is computed.
-
-Now it turns out that $lowpt$ can be used to identify articulation
-points. Suppose $a,v,w$ are distinct vertices in $G$ such that $(a,v)$
-is a tree edge and $w$ is not a descendant of $v$. If $d[lowpt(v)]
-\geq d[a]$, then $a$ is an articulation point and removal of $a$
-disconnects $v$ and $w$. The reason this works is that if $d[lowpt(v)]
-\geq d[a]$, then we know all paths starting from $v$ stay within the
-sub-tree $T_v$ rooted at $v$. If a path were to escape from the
-sub-tree, then consider the first vertex $w$ in that path outside of
-$T_v$.  $v \Path w$ must be considered for $lowpt(v)$, so $d[lowpt(v)]
-< d[w]$. Now $d[w] < d[a]$ due the structure of the DFS, so
-transitively $d[lowpt(v)] < d[a]$.
-
-\section{The Implementation}
-
-The implementation consists of a recursive DFS-like function named
-\code{biconnect()} and the public interface function
-\code{biconnected\-\_components()}. The \code{Graph} type must be a
-model of \concept{VertexListGraph} and of \concept{IncidenceGraph}.
-The result of the algorithm is recorded in the \code{ComponentMap},
-which maps edges to the biconnected component that they belong to
-(components are labeled with integers from zero on up).  The
-\code{ComponentMap} type must be a model of
-\concept{WritablePropertyMap}, which the graph's
-\code{edge\-\_descriptor} type as the key type and an unsigned integer
-type as the value type. We do not record which component each vertex
-belongs to because vertices that are articulation points belong to
-multiple biconnected components.  The number of biconnected components
-is returned in the \code{num\_components} parameter. The
-\code{discover\_time} parameter is used internally to keep track of
-the DFS discover time for each vertex. It must be a
-\concept{ReadWritePropertyMap} with the graph's
-\code{vertex\_\-descriptor} type as the key type and an unsigned
-integer as the value type. The \code{lowpt} parameter is used
-internally to keep track of the $d[lowpt(v)]$ for each vertex $v$.  It
-must be a \concept{ReadWritePropertyMap} with the graph's
-\code{vertex\_\-descriptor} type is the key type and the value type is
-the same unsigned integer type as the value type in the
-\code{discover\-\_time} map.

-
-The first step of the algorithm is to initialize the discover times of
-all the vertices to infinity. This marks the vertices as undiscovered.

-  put(discover_time, *wi, infinity);
-@}
-
-\noindent Next we invoke \code{biconnect()} on every vertex in the
-graph, making sure that all connected components within the graph are
-searched (\code{biconnect()} only processes a single connected
-component).

-
-The recursive \code{biconnect()} function is shown below.  The
-\code{v} parameter is where the DFS is started.  The \code{u}
-parameter is the parent of \code{v} in the DFS-tree if \code{at\_top
-== false} or if \code{at\_top == true} the \code{u} is not used.
-\code{S} is a stack of edges that is used to collect all edges in a
-biconnected component. The way this works is that on ``the way down''
-edges are pushed into the stack.  ``On the way back up'', when an
-articulation point $v$ is found (identified because $d[lowpt(w)] \geq
-d[v]$) we know that a contiguous portion of the stack (starting at the
-top) contains the edges in the sub-tree $T_v$ which is the biconnected
-component.  We therefore pop these edges off of the stack (until we
-find an edge $e$ where $d[lowpt(source(e))] < d[w]$) and mark them as
-belonging to the same component. The code below also includes the
-bookkeeping details such as recording the discover times and computing
-$lowpt$. When a back edge $(v,w)$ is encountered, we do not use
-$lowpt(w)$ in calculating $lowpt(v)$ since $lowpt(w)$ has not yet been
-computed. Also, we ignore the edge $(v,w)$ if $w$ is the parent of $v$
-in the DFS-tree, meaning that $(w,v)$ has already been examined and
-categorized as a tree edge (not a back edge).

-<a href="#1">[1]</a> that is defined by the clockwise ordering of adjacent

-The function <tt>boyer_myrvold_planarity_test</tt> implements the planarity
-testing/embedding algorithm of Boyer and Myrvold
-[<a href="./bibliography.html#boyermyrvold04">70</a>].
-<tt>boyer_myrvold_planarity_test</tt> returns <tt>true</tt> if the input graph
-is planar and <tt>false</tt> otherwise. As a side-effect of this test, a planar
-embedding can be constructed if the graph is planar or a minimal set of edges
-that form a <a href = "./planar_graphs.html#kuratowskisubgraphs">Kuratowski
-subgraph</a> can be found if the graph is not planar.
-<tt>boyer_myrvold_planarity_test</tt> uses named parameter arguments (courtesy
-of the <a href="../../parameter/doc/html/index.html">Boost.Parameter</a>
-library) to specify what the function actually does. Some examples are:
-
-<ul>
-<li>Testing whether or not a graph is planar:
-<pre>
-bool is_planar = boyer_myrvold_planarity_test(g);
-</pre>
-
-<li>Computing a planar embedding for a graph if it is planar, otherwise finding
-a set of edges that forms an obstructing Kuratowski subgraph:
-<pre>
-if (boyer_myrvold_planarity_test(boyer_myrvold_params::graph = g,
-                                 boyer_myrvold_params::embedding = embedding_pmap,
-                                 boyer_myrvold_params::kuratowski_subgraph = out_itr
-                                 )
-    )
-{
-  //do something with the embedding in embedding_pmap
-}
-else
-{
-  //do something with the kuratowski subgraph output to out_itr
-}
-</pre>
-</ul>
-
-<p>
-The parameters passed to <tt>boyer_myrvold_planarity_test</tt> in the examples
-above do more than just carry the data structures used for input and output -
-the algorithm is optimized at compile time based on which parameters are
-present. A complete list of parameters accepted and their interactions are
-described below.
-<p>
-<tt>boyer_myrvold_planarity_test</tt> accepts as input any undirected graph,
-even those with self-loops and multiple edges.
-However, many planar graph drawing algorithms make additional restrictions
-on the structure of the input graph - for example, requiring that the input
-graph is connected, biconnected, or even maximal planar (triangulated.)
-Fortunately, any planar graph on <i>n</i> vertices that lacks one of these
-properties can be augmented with additional edges so that it satisfies that
-property in <i>O(n)</i> time - the functions
-<tt><a href="./make_connected.html">make_connected</a></tt>,
-<tt><a href="./make_biconnected_planar.html">make_biconnected_planar</a></tt>,
-and <tt><a href="./make_maximal_planar.html">make_maximal_planar</a></tt>
-exist for this purpose. If the graph drawing algorithm you're using requires,
-say, a biconnected graph, then you must make your input graph biconnected
-<i>before</i> passing it into <tt>boyer_myrvold_planarity_test</tt> so that the
-computed planar embedding includes these additional edges. This may require
-more than one call to <tt>boyer_myrvold_planarity_test</tt> depending on the
-structure of the graph you begin with, since both
-<tt>make_biconnected_planar</tt> and <tt>make_maximal_planar</tt> require a
-planar embedding of the existing graph as an input parameter.
-
-<p><p>
-The named parameters accepted by <tt>boyer_myrvold_planarity_test</tt> are:
-
-<ul>
-<li><b><tt>graph</tt></b> : The input graph - this is the only required
-parameter.
-<li><b><tt>vertex_index_map</tt></b> : A mapping from vertices of the input
-graph to indexes in the range <tt>[0..num_vertices(g))</tt>. If this parameter
-is not provided, the vertex index map is assumed to be available as an interior
-property of the graph, accessible by calling <tt>get(vertex_index, g)</tt>.
-<li><b><tt>edge_index_map</tt></b>: A mapping from the edges of the input graph
-to indexes in the range <tt>[0..num_edges(g))</tt>. This parameter is only
-needed if the <tt>kuratowski_subgraph</tt> argument is provided. If the
-<tt>kuratowski_subgraph</tt> argument is provided and this parameter is not
-provided, the EdgeIndexMap is assumed to be available as an interior property
-accessible by calling <tt>get(edge_index, g)</tt>.
-<li><b><tt>embedding</tt></b> : If the graph is planar, this will be populated
-with a mapping from vertices to the clockwise order of neighbors in the planar
-embedding.
-<li><b><tt>kuratowski_subgraph</tt></b> : If the graph is not planar, a minimal
-set of edges that form the obstructing Kuratowski subgraph will be written to
-this iterator.
-</ul>
-
-These named parameters all belong to the namespace
-<tt>boyer_myrvold_params</tt>. See below for more information on the concepts
-required for these arguments.
-
-<H3>Verifying the output</H3>
-
-Whether or not the input graph is planar, <tt>boyer_myrvold_planarity_test</tt>
-can produce a certificate that can be automatically checked to verify that the
-function is working properly.
-<p>
-If the graph is planar, a planar embedding can be produced. The
-planar embedding can be verified by passing it to a plane drawing routine
-(such as <tt><a href="straight_line_drawing.html">
-chrobak_payne_straight_line_drawing</a></tt>) and using the function
-<tt><a href="is_straight_line_drawing.html">is_straight_line_drawing</a></tt>
-to verify that the resulting graph is planar.

-<P>The <TT>boykov_kolmogorov_max_flow()</TT> function calculates the maximum
-flow of a network. See Section <A HREF="graph_theory_review.html#sec:network-flow-algorithms">Network

-also calculates the flow values <I>f(u,v)</I> for all <I>(u,v)</I> in
-<I>E</I>, which are returned in the form of the residual capacity
-<I>r(u,v) = c(u,v) - f(u,v)</I>.

-<P><B>Requirements:</B><BR>The directed graph <I>G=(V,E)</I> that

-</P>
-
-<P>Remarks: While the push-relabel method states that each edge in <I>E<SUP>T</SUP></I>
-has to have capacity of 0, the reverse edges for this algorithm ARE
-allowed to carry capacities. If there are already reverse edges in
-the input Graph <I><FONT FACE="Courier New, monospace">G</FONT></I>,
-those can be used. This can halve the amount of edges and will
-noticeably increase the performance.</P>
-
-<P>
-<B>Algorithm description:</B><BR>The Boykov-Kolmogorov max-flow (or often
-BK max-flow) algorithm is a variety of the augmenting-path algorithm. Standard
-augmenting path algorithms find shortest paths from source to sink vertex and
-augment them by subtracting the bottleneck capacity found on that path from the
-residual capacities of each edge and adding it to the total flow. Additionally
-the minimum capacity is added to the residual capacity of the reverse edges. If
-no more paths in the residual-edge tree are found, the algorithm terminates.
-Instead of finding a new shortest path from source to sink in the graph in each
-iteration, the Boykov-Kolmogorov algorithm keeps the already found paths as
-follows:</P>
-
-<P>The algorithm builds up two search trees, a source-tree and a
-sink-tree. Each vertex has a label (stored in <I>ColorMap</I>) to
-which tree it belongs and a status-flag if this vertex is active or
-passive. In the beginning of the algorithm only the source and the
-sink are colored (source==black, sink==white) and have active status.
-All other vertices are colored gray. The algorithm consists of three
-phases:</P>
-<P><I>grow-phase</I>: In this phase active vertices are allowed to
-acquire neighbor vertices that are connected through an edge that has
-a capacity-value greater than zero. Acquiring means that those vertices
-become active and belong now to the search tree of the current
-active vertex. If there are no more valid connections to neighbor
-vertices, the current vertex becomes passive and the grow phase
-continues with the next active vertex. The grow phase terminates if
-there are no more active vertices left or a vertex discovers a vertex
-from the other search tree through an unsaturated edge. In this case
-a path from source to sink is found.</P>
-<P><I>augment-phase</I>: This phase augments the path that was found
-in the grow phase. First it finds the bottleneck capacity of the
-found path, and then it updates the residual-capacity of the edges
-from this path by subtracting the bottleneck capacity from the
-residual capacity. Furthermore the residual capacity of the reverse
-edges are updated by adding the bottleneck capacity. This phase can
-destroy the built up search trees, as it creates at least one
-saturated edge. That means, that the search trees collapse to
-forests, because a condition for the search trees is, that each
-vertex in them has a valid (=non-saturated) connection to a terminal.</P>
-<P><I>adoption-phase</I>: Here the search trees are reconstructed. A
-simple solution would be to mark all vertices coming after the first
-orphan in the found path free vertices (gray). A more sophisticated
-solution is to give those orphans new parents: The neighbor vertices
-are checked if they have a valid connection to the same terminal like
-this vertex had (a path with unsaturated edges). If there is one,
-this vertex becomes the new parent of the current orphan and this
-forest is re-included into the search tree. If no new valid parent is
-found, this vertex becomes a free vertex (marked gray), and it's
-children become orphans. The adoption phase terminates if there are
-no more orphans.</P>
-<P><IMG SRC="figs/bk_max_flow.gif" NAME="Grafik2" ALIGN=LEFT WIDTH=827 HEIGHT=311 BORDER=0><BR CLEAR=LEFT><B>Details:</B></P>
-<UL>
-	<LI><P>Marking heuristics: A timestamp is stored for each vertex
-	which shows in which iteration of the algorithm the distance to the
-	corresponding terminal was calculated.
-	</P>
-	<UL>
-		<LI><P>This distance is used and gets calculated in the
-		adoption-phase. In order to find a valid new parent for an orphan,
-		the possible parent is checked for a connection to the terminal to
-		which tree it belongs. If there is such a connection, the path is
-		tagged with the current time-stamp, and the distance value. If
-		another orphan has to find a parent and it comes across a vertex
-		with a current timestamp, this information is used.</P>
-		<LI><P>The distance is also used in the grow-phase. If a vertex
-		comes across another vertex of the same tree while searching for
-		new vertices, the other's distance is compared to its distance. If
-		it is smaller, that other vertex becomes the new parent of the
-		current. This can decrease the length of the search paths, and so
-		amount of adoptions.</P>
-	</UL>
-	<LI><P>Ordering of orphans: As described above, the augment-phase
-	and the adoption phase can create orphans. The orphans the
-	augment-phase generates, are ordered according to their distance to
-	the terminals (smallest first). This combined with the
-	distance/timestamp heuristics results in the possibility for not
-	having to recheck terminal-connections too often. New orphans which
-	are generated in adoption phase are processed before orphans from
-	the main queue for the same reason.</P>
-</UL>
-<P><BR><B>Implementation notes:</B></P>
-<P>The algorithm is mainly implemented as described by Boykov and Kolmogorov in
-[<a href="bibliography.html#boykov-kolmogorov04">69</a>]. An extended version
-can be found in the PhD Thesis of Kolmogorov [<A HREF="bibliography.html#kolmogorov03">68</a>].
-The following changes are made to improve performance:</P>
-<UL>
-	<LI>initialization: the algorithm first augments all paths from
-	source-&gt;sink and all paths from source-&gt;VERTEX-&gt;sink. This
-	improves especially graph-cuts used in image vision where nearly
-	each vertex has a source and sink connect. During this step, all
-	vertices that have an unsaturated connection from source are added
-	to the active vertex list and so the source is not.</LI>
-	<LI>active vertices: Boykov-Kolmogorov uses two lists for active nodes
-	and states that new active vertices are added to the rear of the
-	second. Fetching an active vertex is done from the beginning of the
-	first list. If the first list is empty, it is exchanged by the
-	second. This implementation uses just one list.</LI>
-	<LI>grow-phase: In the grow phase the first vertex in the
-	active-list is taken and all outgoing edges are checked if they are
-	unsaturated. This decreases performance for graphs with high-edge
-	density. This implementation stores the last accessed edge and
-	continues with it, if the first vertex in the active-list is the
-	same one as during the last grow-phase.</LI>

-The <tt>breadth_first_search()</tt> function performs a breadth-first
-traversal [<a href="./bibliography.html#moore59">49</a>] of a directed
-or undirected graph.  A breadth-first traversal visits vertices that
-are closer to the source before visiting vertices that are further
-away. In this context ``distance'' is defined as the number of edges
-in the shortest path from the source vertex. The
-<tt>breadth_first_search()</tt> function can be used to compute the
-shortest path from the source to all reachable vertices and the
-resulting shortest-path distances. For more definitions related to BFS
-see section <a href="./graph_theory_review.html#sec:bfs-algorithm">
-Breadth-First Search</a>.
-</p>
-
-<p>
-BFS uses two data structures to to implement the traversal: a color
-marker for each vertex and a queue. White vertices are undiscovered
-while gray vertices are discovered but have undiscovered adjacent
-vertices. Black vertices are discovered and are adjacent to only other
-black or gray vertices.  The algorithm proceeds by removing a vertex
-</i>u</i> from the queue and examining each out-edge <i>(u,v)</i>. If an
-adjacent vertex <i>v</i> is not already discovered, it is colored gray and
-placed in the queue. After all of the out-edges are examined, vertex
-<i>u</i> is colored black and the process is repeated.  Pseudo-code for the
-BFS algorithm is a listed below.

-<h1>Bundled Properties</h1>
-
-<p>Class templates <code><a
-href="adjacency_list.html">adjacency_list</a></code> and
-<code><a href="adjacency_matrix.html">adjacency_matrix</a></code> support
-the introduction of named properties via <a
-href="using_adjacency_list.html#sec:adjacency-list-properties">internal
-properties</a>. However, this method is cumbersome in many uses,
-where it would be more intuitive to just specify a structure or
-class that contains internal properties for edges or
-vertices. Bundled properties allow one to use
-<code>adjacency_list</code> and <code>adjacency_matrix</code> in this
-manner, providing a simple
-way to introduce and access any number of internal properties
-for vertices and edges.</p>
-
-<p>One can introduce bundled properties into an
-either graph type by providing a user-defined class
-type for the <code>VertexProperties</code> or
-<code>EdgeProperties</code> template arguments. The user-defined
-class may alternatively be placed at the end of a
-<code>property</code> list, replacing the (implicit)
-<code>boost::no_property</code> argument.</p>
-
-<h2>Example: Route planning</h2>
-<p>Consider the implementation of a simple route planner that
-  should find the shortest directions from one city to another
-  via a set of highways. The vertices of the graph are cities,
-  and we may wish to store several bits of information about the
-  city within each vertex:</p>
-<pre>
-struct City
-{
-  string name;
-  int population;
-  vector&lt;int&gt; zipcodes;
-};
-</pre>
-
-<p>
-The edges in the graph represent highways, which also have several interesting
-attributes:
-</p>
-
-<pre>
-struct Highway
-{
-  string name;
-  double miles;
-  int speed_limit;
-  int lanes;
-  bool divided;
-};
-</pre>
-
-<p>With bundled properties, we can directly use the <code>City</code> and
-<code>Highway</code> structures to define the graph:</p>
-<pre>
-typedef boost::adjacency_list&lt;
-    boost::listS, boost::vecS, boost::bidirectionalS,
-    City, Highway&gt;
-  Map;
-</pre>
-
-<p>Without bundled properties, translating this example directly
-into an instantiation of <code>adjacency_list</code> would
-involve several custom properties and would result in a type
-like this:</p>
-<pre>
-typedef boost::adjacency_list&lt;
-    boost::listS, boost::vecS, boost::bidirectionalS,
-    // Vertex properties
-    boost::property&lt;boost::vertex_name_t, std::string,
-    boost::property&lt;population_t, int,
-    boost::property&lt;zipcodes_t, std::vector&lt;int&gt; &gt; &gt; &gt;,
-    // Edge properties
-    boost::property&lt;boost::edge_name_t, std::string,
-    boost::property&lt;boost::edge_weight_t, double,
-    boost::property&lt;edge_speed_limit_t, int,
-    boost::property&lt;edge_lanes_t, int,
-    boost::property&lt;edge_divided, bool&gt; &gt; &gt; &gt; &gt; &gt;
-  Map;
-</pre>
-
-<p>
-Bundling vertex and edge properties greatly simplifies the declaration of
-graphs.
-</p>
-<p>
-In addition to vertex and edge bundles, we can also bundle properties of the
-graph itself. Suppopse we extend the application to include a portfolio of
-route-planning maps for different countries. In addition to the <code>City</code>
-and <code>Highway</code> bundles above, we can declare a graph bundle,
-<code>Country</Code>.
-</p>
-
-<pre>
-struct Country {
-  string name;
-  bool use_right;   // Drive on the left or right
-  bool use_metric;  // mph or km/h
-};
-</pre>
-
-<p>The graph would now be declared as:</p>
-
-<pre>
-<pre>
-typedef boost::adjacency_list&lt;
-    boost::listS, boost::vecS, boost::bidirectionalS,
-    City, Highway, Country&gt;
-  Map;
-</pre>
-</pre>
-
-<h2>Accessing bundled properties</h2>
-<p>To access a bundled property for a particular edge or vertex,
-  subscript your graph with the descriptor of the edge or vertex
-  whose bundled property you wish to access. For instance:</p>
-<pre>
-Map map; // load the map
-Map::vertex_descriptor v = *vertices(map).first;
-map[v].name = "Troy";
-map[v].population = 49170;
-map[v].zipcodes.push_back(12180);
-Map::edge_descriptor e = *out_edges(v, map).first;
-map[e].name = "I-87";
-map[e].miles = 10.;
-map[e].speed_limit = 65;
-map[e].lanes = 4;
-map[e].divided = true;
-</pre>
-
-<p>
-The graph bundle, since it does not correspond to a vertex or edge descripor
-is accessed using the graph_bundle object as a key.
-</p>
-
-<pre>
-map[graph_bundle].name = "United States";
-map[graph_bundle].use_right = true;
-map[graph_bundle].use_metric = false;
-</pre>
-
-
-<h2>Properties maps from bundled properties</h2>
-<p>Often one needs to create a property map from an internal
-  property for use in a generic algorithm. For instance, using the
-  graph without bundled properties we might invoke <a
-    href="dijkstra_shortest_paths.html">Dijkstra's shortest
-    paths</a> algorithm like this:</p>
-<pre>
-vector&lt;double&gt; distances(num_vertices(map));
-dijkstra_shortest_paths(map, from,
-      weight_map(get(edge_length, map))
-      .distance_map(make_iterator_property_map(distances.begin(),
-                                               get(vertex_index, map))));
-</pre>
-
-<p>With bundled properties, we can just pass a <em>member pointer</em>
-as the property for <code>get</code>. The equivalent example using bundled
-properties is:</p>
-<pre>
-vector&lt;double&gt; distances(num_vertices(map));
-dijkstra_shortest_paths(map, from,
-      weight_map(get(<font color="#ff0000">&amp;Highway::miles</font>, map))
-      .distance_map(make_iterator_property_map(distances.begin(),
-                                               get(vertex_index, map))));
-</pre>
-
-<p>The type of the returned property map is <code>property_map&lt;Map, double Highway::*&gt;::type</code>
-or <code>property_map&lt;Map, double Highway::*&gt;::const_type</code>, depending on whether the graph
-<code>map</code> is non-constant or constant.
-
-<p> You may also access the entire vertex or edge bundle as a property map
-using the <code>vertex_bundle</code> or <code>edge_bundle</code> properties,
-respectively. For instance, the property map returned by <code>get(vertex_bundle, map)</code> is
-an <a href="../../property_map/doc/LvaluePropertyMap.html">Lvalue Property Map</a> providing access to the
-<code>City</code> values stored in each vertex.
-
-<h2>Property maps for a graph bundle</h2>
-There is currently no support for creating property maps from the bundled
-properties of a graph.
-
-<h2>Getting the type of bundled properties</h2>
-
-<p>To get the type of the vertex or edge bundle for a given graph
-type <tt>Graph</tt>, you can use the trait
-classes <tt>vertex_bundle_type</tt>
-and <tt>edge_bundle_type</tt>. The
-type <tt>vertex_bundle_type&lt;Graph&gt;::type</tt> will be the
-type bundled with vertices (or <tt>no_vertex_bundle</tt> if the
-graph supports bundles but no vertex bundle
-exists). Likewise, <tt>edge_bundle_type&lt;Graph&gt;::type</tt>
-will be the type bundled with edges (or <tt>no_edge_bundle</tt> if
-no edge bundle exists).</p>
-
-<h2>Compatibility</h2> <p>Bundled properties will only work
-properly on compilers that support class template partial
-specialization.</p>

-Algorithms</a> and <a
-href="http://citeseer.ist.psu.edu/alberts98software.html">A Software
-Library of Dynamic Graph Algorithms</a>.
-
-<li>Polish up code/docs for pending items and champion the formal
-review. The pending items are:</li>
-  <ul>
-   <li><tt>container_traits.hpp</tt> (this should also include
-     the work Matt Austern is doing on this topic)</li>
-
-   <li>The queues and heaps: <tt>queue.hpp</tt>,

-  <ul>
-   <li> Is the graph planar?</li>
-   <li> &quot;Walk around the block&quot; and similar open and closed neighborhood
-traversals. Note that edge traversals need to resolve to particular ends
-and sides (see below), not just to the edge as a whole.</li>
-   <li> Given a point, find the nearest vertex, edge, or bounded polygon.
-Again, edges are viewed as having left and right sides.</li>
-   <li> Given a line segment, find intersecting vertices, edges, or bounded
-polygons.</li>

-write an interface for Qhull with the BGL.  <a
-href="http://www.qhull.org/">Qhull</a> computes the
-convex hull, Delaunay triangulation, Voronoi diagram, and halfspace
-intersection about a point.  Qhull runs in 2-d, 3-d, 4-d, and higher

-
-<li>Analyze the algorithms that do not yet have visitors, and
-  come up with visitor interfaces for them.</li>
-
-<li>Add a check in the adjacency_list class to make sure
-  all the vertex property template arguments have kind=vertex_property_tag
-  and all edge property template arguments have kind=edge_property_tag.</li>
-
-<li>Clean up the output functions in graph_utility.hpp to
-  use streams, and document all the utility functions. Replace
-  the random number stuff with calls to the boost random number generator.</li>
-
-<li>Modularize the tests in test/graph.cpp to apply to particular

-  href="../example/miles_span.cpp"><tt>examples/miles_span.cpp</tt></a>
-  is a start.</li>
-
-<li>Further testing of the <tt>subgraph</tt> class and add more
-   features.</li>
-
-<li>Implement a minimum-cost maximum-flow algorithm.</li>
-
-<li>Make the <tt>type</tt> of all (internal) property maps convertible to the <tt>const_type</tt> of the property maps.<li>

-    <h1>Compressed Sparse Row Graph</h1>
-
-    <p>The class template <code>compressed_sparse_row_graph</code> is
-    a graph class that uses the compact Compressed Sparse Row (CSR)
-    format to store directed (and bidirectional) graphs. While CSR graphs have
-    much less
-    overhead than many other graph formats (e.g., <a
-    href="adjacency_list.html"><code>adjacency_list</code></a>), they
-    do not provide any mutability: one cannot add or remove vertices
-    or edges from a CSR graph. Use this format in high-performance
-    applications or for very large graphs that you do not need to
-    change.</p>
-
-    <p>The CSR format stores vertices and edges in separate arrays,
-    with the indices into these arrays corresponding to the identifier
-    for the vertex or edge, respectively. The edge array is sorted by
-    the source of each edge, but contains only the targets for the
-    edges. The vertex array stores offsets into the edge array,
-    providing the offset of the first edge outgoing from each
-    vertex. Iteration over the out-edges for the <i>i</i><sup>th</sup>
-    vertex in the graph is achieved by
-    visiting <tt>edge_array[vertex_array[i]]</tt>,
-    <tt>edge_array[vertex_array[i]+1]</tt>,
-    ..., <tt>edge_array[vertex_array[i+1]]</tt>. This format minimizes
-    memory use to <i>O(n + m)</i>, where <i>n</i> and <i>m</i> are the
-    number of vertices and edges, respectively. The constants
-    multiplied by <i>n</i> and <i>m</i> are based on the size of the
-    integers needed to represent indices into the edge and vertex
-    arrays, respectively, which can be controlled using
-    the <a href="#template-parms">template parameters</a>.  The
-    <tt>Directed</tt> template parameter controls whether one edge direction
-    (the default) or both directions are stored.  A directed CSR graph has
-    <tt>Directed</tt> = <tt>directedS</tt> and a bidirectional CSR graph (with
-    a limited set of constructors)
-    has <tt>Directed</tt> = <tt>bidirectionalS</tt>.</p>

-
-    <p>The <tt>compressed_sparse_row_graph</tt> class template models
-    (i.e., implements the requirements of) many of the
-    BGL <a href="graph_concepts.html">graph concepts</a>, allowing it

-
-    <a name="template-parms"></a><h2>Template Parameters</h2>
-
-    <p>The <tt>compressed_sparse_row_graph</tt> class has several
-      template parameters that can customize the layout in memory and
-      what properties are attached to the graph itself. All
-      parameters have defaults, so users interested only in the
-      structure of a graph can use the
-      type <tt>compressed_sparse_row_graph&lt;&gt;</tt> and ignore
-      the parameters.</p>
-
-    <b>Parameters</b>
-    <br>
-    <br>
-
-    <a name="Directed"></a><code>Directed</code>
-      <blockquote>
-        A selector that determines whether the graph will be directed,
-        bidirectional or undirected. At this time, the CSR graph type
-        only supports directed and bidirectional graphs, so this value must
-        be either <code>boost::directedS</code> or
-        <code>boost::bidirectionalS</code>.<br>
-        <b>Default</b>: <code>boost::directedS</code>
-      </blockquote>
-
-    <a name="VertexProperty"></a><code>VertexProperty</code>
-      <blockquote>
-        A class type that will be
-        attached to each vertex in the graph. If this value
-        is <code>void</code>, no properties will be attached to
-        the vertices of the graph.<br>
-        <b>Default</b>: <code>void</code>
-      </blockquote>
-
-    <a name="EdgeProperty"></a><code>EdgeProperty</code>
-    <blockquote>
-      A class type that will be attached to each edge in the graph. If
-        this value is <code>void</code>, no properties will be
-        attached to the edges of the graph.<br>
-        <b>Default</b>: <code>void</code>
-    </blockquote>
-
-    <a name="GraphProperty"></a><code>GraphProperty</code>
-    <blockquote>
-      A nested set
-        of <code>property</code> templates that describe the
-        properties of the graph itself.  If this value
-        is <code>no_property</code>, no properties will be attached to
-        the graph.<br>
-        <b>Default</b>: <code>no_property</code>
-    </blockquote>
-
-    <a name="Vertex"></a><code>Vertex</code>
-    <blockquote>
-      An unsigned integral type that will be
-      used as both the index into the array of vertices and as the
-      vertex descriptor itself. Larger types permit the CSR graph to
-      store more vertices; smaller types reduce the storage required
-      per vertex.<br>
-        <b>Default</b>: <code>std::size_t</code>
-    </blockquote>
-
-    <a name="EdgeIndex"></a><code>EdgeIndex</code>
-    <blockquote>
-      An unsigned integral type that will be used as the index into
-        the array of edges. As with the <code>Vertex</code> parameter,
-        larger types permit more edges whereas smaller types reduce
-        the amount of storage needed per
-        edge. The <code>EdgeIndex</code> type shall not be smaller
-        than the <code>Vertex</code> type, but it may be larger. For
-        instance, <code>Vertex</code> may be a 16-bit integer
-        (allowing 32,767 vertices in the graph)
-        whereas <code>EdgeIndex</code> could then be a 32-bit integer
-        to allow a complete graph to be stored in the CSR format.<br>
-        <b>Default</b>: <code>Vertex</code>
-    </blockquote>
-
-    <a name="properties"></a><h2>Interior Properties</h2>
-
-    <p> The <tt>compressed_sparse_row_graph</tt> allows properties to

-<H1>Constructing graph algorithms with BGL</H1>
-
-<P>
-The <I>main</I> goal of  BGL is not to provide a nice graph class, or
-to provide a comprehensive set of reusable graph algorithms (though
-these are goals). The main goal of BGL is to encourage others to
-write reusable graph algorithms. By reusable we mean maximally
-reusable.  Generic programming is a methodology for making algorithms
-maximally reusable, and in this section we will discuss how to apply
-generic programming to constructing graph algorithms.
-
-<P>
-To illustrate the generic programming process we will step though the
-construction of a graph coloring algorithm. The graph coloring problem
-(or more specifically, the vertex coloring problem) is to label each
-vertex in a graph <i>G</i> with a color such that no two adjacent
-vertices are labeled with the same color and such that the minimum
-number of colors are used. In general, the graph coloring problem is
-NP-complete, and therefore it is impossible to find an optimal
-solution in a reasonable amount of time. However, there are many
-algorithms that use heuristics to find colorings that are close to the
-minimum.
-
-<P>
-The particular algorithm we present here is based on the linear time
-<TT>SEQ</TT> subroutine that is used in the estimation of sparse
-Jacobian and Hessian matrices&nbsp;[<A
-HREF="bibliography.html#curtis74:_jacob">9</A>,<A
-HREF="bibliography.html#coleman84:_estim_jacob">7</A>,<A
-HREF="bibliography.html#coleman85:_algor">6</A>].  This algorithm
-visits all of the vertices in the graph according to the order defined
-by the input order. At each vertex the algorithm marks the colors of
-the adjacent vertices, and then chooses the smallest unmarked color
-for the color of the current vertex. If all of the colors are already
-marked, a new color is created.  A color is considered marked if its
-mark number is equal to the current vertex number. This saves the
-trouble of having to reset the marks for each vertex. The
-effectiveness of this algorithm is highly dependent on the input
-vertex order. There are several ordering algorithms, including the
-<I>largest-first</I>&nbsp;[<A HREF="bibliography.html#welsch67">31</A>],
-<I>smallest-last</I>&nbsp;[<a
-href="bibliography.html#matula72:_graph_theory_computing">29</a>], and
-<I>incidence degree</I>&nbsp;[<a
-href="bibliography.html#brelaz79:_new">32</a>] algorithms, which
-improve the effectiveness of this coloring algorithm.
-
-<P>
-The first decision to make when constructing a generic graph algorithm
-is to decide what graph operations are necessary for implementing the
-algorithm, and which graph concepts the operations map to.  In this
-algorithm we will need to traverse through all of the vertices to
-intialize the vertex colors. We also need to access the adjacent
-vertices. Therefore, we will choose the <a
-href="./VertexListGraph.html">VertexListGraph</a> concept because it
-is the minimum concept that includes these operations.  The graph type
-will be parameterized in the template function for this algorithm. We
-do not restrict the graph type to a particular graph class, such as
-the BGL <a href="./adjacency_list.html"><TT>adjacency_list</TT></a>,
-for this would drastically limit the reusability of the algorithm (as
-most algorithms written to date are). We do restrict the graph type to
-those types that model <a
-href="./VertexListGraph.html">VertexListGraph</a>. This is enforced by
-the use of those graph operations in the algorithm, and furthermore by
-our explicit requirement added as a concept check with
-<TT>BOOST_CONCEPT_ASSERT()</TT> (see Section <A
-HREF="../../concept_check/concept_check.htm">Concept
-Checking</A> for more details about concept checking).
-
-<P>
-Next we need to think about what vertex or edge properties will be
-used in the algorithm. In this case, the only property is vertex
-color. The most flexible way to specify access to vertex color is to
-use the propery map interface. This gives the user of the
-algorithm the ability to decide how they want to store the properties.
-Since we will need to both read and write the colors we specify the
-requirements as <a
-href="../../property_map/doc/ReadWritePropertyMap.html">ReadWritePropertyMap</a>. The
-<TT>key_type</TT> of the color map must be the
-<TT>vertex_descriptor</TT> from the graph, and the <TT>value_type</TT>
-must be some kind of integer. We also specify the interface for the
-<TT>order</TT> parameter as a property map, in this case a <a
-href="../../property_map/doc/ReadablePropertyMap.html">ReadablePropertyMap</a>. For
-order, the <TT>key_type</TT> is an integer offset and the
-<TT>value_type</TT> is a <TT>vertex_descriptor</TT>. Again we enforce
-these requirements with concept checks. The return value of this
-algorithm is the number of colors that were needed to color the graph,
-hence the return type of the function is the graph's
-<TT>vertices_size_type</TT>. The following code shows the interface for our
-graph algorithm as a template function, the concept checks, and some
-typedefs. The implementation is straightforward, the only step not
-discussed above is the color initialization step, where we set the
-color of all the vertices to "uncolored."

-href="bibliography.html#george71:fem">45</a> ] is to reduce the <a
-href="./bandwidth.html">bandwidth</a> of a graph by reordering the
-indices assigned to each vertex.  The Cuthill-Mckee ordering algorithm
-works by a local minimization of the i-th bandwidths. The vertices are
-basically assigned a breadth-first search order, except that at each
-step, the adjacent vertices are placed in the queue in order of
-increasing degree.
-
-<p>
-Version 1 of the algorithm lets the user choose the ``starting
-vertex'', version 2 finds a good starting vertex using the
-pseudo-peripheral pair heuristic (among each component), while version 3
-contains the starting nodes for each vertex in the deque.  The choice of the
-``starting vertex'' can have a significant effect on the quality of the
-ordering.  For versions 2 and 3, <tt>find_starting_vertex</tt> will be called
-for each component in the graph, increasing run time significantly.
-</p>
-
-<p>
-The output of the algorithm are the vertices in the new ordering.
-Depending on what kind of output iterator you use, you can get either
-the Cuthill-Mckee ordering or the reverse Cuthill-McKee ordering.  For
-example, if you store the output into a vector using the vector's
-reverse iterator, then you get the reverse Cuthill-McKee ordering.
-</p>
-
-<pre>
-  std::vector&lt;vertex_descriptor&gt; inv_perm(num_vertices(G));
-  cuthill_mckee_ordering(G, inv_perm.rbegin(), ...);
-</pre>
-
-<p>
-Either way, storing the output into a vector gives you the
-permutation from the new ordering to the old ordering.
-</p>
-
-<pre>
-  inv_perm[new_index[u]] == u
-</pre>
-
-<p>
-Often times, it is the opposite permutation that you want, the
-permutation from the old index to the new index. This can easily be
-computed in the following way.
-</p>
-
-<pre>
-  for (size_type i = 0; i != inv_perm.size(); ++i)
-    perm[old_index[inv_perm[i]]] = i;

-</PRE>
-
-<P>
-The <tt>cycle_canceling()</tt> function calculates the minimum cost flow of a network with given flow. See Section <a
-href="./graph_theory_review.html#sec:network-flow-algorithms">Network
-Flow Algorithms</a> for a description of maximum flow.
-For given flow values <i> f(u,v)</i>  function minimizes flow cost in such a way, that for each <i>v in V</i> the
- <i> sum<sub> u in V</sub>  f(v,u) </i> is preserved. Particularly if the input flow was the maximum flow, the function produces min cost max flow.
-
-
- The function calculates the flow values <i>f(u,v)</i> for all <i>(u,v)</i> in
-<i>E</i>, which are returned in the form of the residual capacity
-<i>r(u,v) = c(u,v) - f(u,v)</i>.
-
-<p>
-There are several special requirements on the input graph and property
-map parameters for this algorithm. First, the directed graph
-<i>G=(V,E)</i> that represents the network must be augmented to
-include the reverse edge for every edge in <i>E</i>.  That is, the
-input graph should be <i>G<sub>in</sub> = (V,{E U
-E<sup>T</sup>})</i>. The <tt>ReverseEdgeMap</tt> argument <tt>rev</tt>
-must map each edge in the original graph to its reverse edge, that is
-<i>(u,v) -> (v,u)</i> for all <i>(u,v)</i> in <i>E</i>.
-The <tt>WeightMap</tt> has to map each edge from <i>E<sup>T</sup></i> to <i>-weight</i> of its reversed edge.
-Note that edges from <i>E</i> can have negative weights.
-<p>
-If weights in the graph are nonnegative, the
-<a href="./successive_shortest_path_nonnegative_weights.html"><tt>successive_shortest_path_nonnegative_weights()</tt></a>
-might be better choice for min cost max flow.
-
-<p>
-The algorithm is described in <a
-href="./bibliography.html#ahuja93:_network_flows">Network Flows</a>.
-
-<p>
-In each round algorithm augments the negative cycle (in terms of weight) in the residual graph.
-If there is no negative cycle in the network, the cost is optimized.
-
-<p>
-Note that, although we mention capacity in the problem description, the actual algorithm doesn't have to now it.

-This algorithm&nbsp;[<A HREF="bibliography.html#clr90">8</A>] solves
-the single-source shortest-paths problem on a weighted, directed
-acyclic graph (DAG). This algorithm is more efficient for DAG's
-than either the Dijkstra or Bellman-Ford algorithm.
-Use breadth-first search instead of this algorithm
-when all edge weights are equal to one.  For the definition of the
-shortest-path problem see Section <A
-HREF="graph_theory_review.html#sec:shortest-paths-algorithms">Shortest-Paths
-Algorithms</A> for some background to the shortest-path problem.
-</P>
-
-<P>
-There are two main options for obtaining output from the
-<tt>dag_shortest_paths()</tt> function. If you provide a
-distance property map through the <tt>distance_map()</tt> parameter
-then the shortest distance from the source vertex to every other
-vertex in the graph will be recorded in the distance map. Also you can
-record the shortest paths tree in a predecessor map: for each vertex
-<i>u in V</i>, <i>p[u]</i> will be the predecessor of <i>u</i> in
-the shortest paths tree (unless <i>p[u] = u</i>, in which case <i>u</i> is
-either the source or a vertex unreachable from the source).  In
-addition to these two options, the user can provide there own
-custom-made visitor that can takes actions during any of the
-algorithm's event points.</P>

-<p>
-The <tt>depth_first_search()</tt> function performs a depth-first
-traversal of the vertices in a directed graph.  When
-possible, a depth-first traversal chooses a vertex adjacent to the
-current vertex to visit next. If all adjacent vertices have already
-been discovered, or there are no adjacent vertices, then the algorithm
-backtracks to the last vertex that had undiscovered neighbors. Once
-all reachable vertices have been visited, the algorithm selects from
-any remaining undiscovered vertices and continues the traversal. The
-algorithm finishes when all vertices have been visited. Depth-first
-search is useful for categorizing edges in a graph, and for imposing
-an ordering on the vertices. Section <a
-href="./graph_theory_review.html#sec:dfs-algorithm">Depth-First
-Search</a> describes the various properties of DFS and walks through
-an example.
-</p>
-
-<p>
-Similar to BFS, color markers are used to keep track of which vertices
-have been discovered. White marks vertices that have yet to be
-discovered, gray marks a vertex that is discovered but still has
-vertices adjacent to it that are undiscovered. A black vertex is
-discovered vertex that is not adjacent to any white vertices.
-<p>
-
-<p>
-The <tt>depth_first_search()</tt> function invokes user-defined
-actions at certain event-points within the algorithm. This provides a
-mechanism for adapting the generic DFS algorithm to the many
-situations in which it can be used.  In the pseudo-code below, the
-event points for DFS are the labels on
-the right. The user-defined actions must be provided in the form of a
-visitor object, that is, an object whose type meets the requirements
-for a <a href="./DFSVisitor.html">DFS Visitor</a>. In the pseudo-code
-we show the algorithm computing predecessors <i>p</i>, discover time
-<i>d</i> and finish time <i>t</i>.  By default, the
-<tt>depth_first_search()</tt> function does not compute these
-properties, however there are pre-defined visitors such as <a
-href="./predecessor_recorder.html"><tt>predecessor_recorder</tt></a>
-and <a href="./time_stamper.html"><tt>time_stamper</tt></a> that can
-be used to do this.

-This algorithm&nbsp;[<A HREF="bibliography.html#dijkstra59">10</A>,<A
-HREF="bibliography.html#clr90">8</A>] solves the single-source
-shortest-paths problem on a weighted, directed or undirected graph for
-the case where all edge weights are nonnegative.  Use the Bellman-Ford
-algorithm for the case when some edge weights are negative.  Use
-breadth-first search instead of Dijkstra's algorithm when all edge
-weights are equal to one.  For the definition of the shortest-path
-problem see Section <A
-HREF="graph_theory_review.html#sec:shortest-paths-algorithms">Shortest-Paths
-Algorithms</A> for some background to the shortest-path problem.
-</P>
-
-<P>
-There are two main options for obtaining output from the
-<tt>dijkstra_shortest_paths()</tt> function. If you provide a
-distance property map through the <tt>distance_map()</tt> parameter
-then the shortest distance from the source vertex to every other
-vertex in the graph will be recorded in the distance map. Also you can
-record the shortest paths tree in a predecessor map: for each vertex
-<i>u in V</i>, <i>p[u]</i> will be the predecessor of <i>u</i> in
-the shortest paths tree (unless <i>p[u] = u</i>, in which case <i>u</i> is
-either the source or a vertex unreachable from the source).  In
-addition to these two options, the user can provide their own
-custom-made visitor that takes actions during any of the
-algorithm's event points.</P>
-
-<P>
-Dijkstra's algorithm finds all the shortest paths from the source
-vertex to every other vertex by iteratively ``growing'' the set of
-vertices <i>S</i> to which it knows the shortest path. At each step of
-the algorithm, the next vertex added to <i>S</i> is determined by a
-priority queue.  The queue contains the vertices in <i>V - S</i><a
-href="#1">[1]</a> prioritized by their distance label, which is the
-length of the shortest path seen so far for each vertex. The vertex
-<i>u</i> at the top of the priority queue is then added to <i>S</i>,
-and each of its out-edges is relaxed: if the distance to <i>u</i> plus
-the weight of the out-edge <i>(u,v)</i> is less than the distance
-label for <i>v</i> then the estimated distance for vertex <i>v</i> is
-reduced.  The algorithm then loops back, processing the next vertex at
-the top of the priority queue. The algorithm finishes when the
-priority queue is empty.
-</P>
-<P>
-The algorithm uses color markers (white, gray, and black) to keep
-track of which set each vertex is in. Vertices colored black are in
-<i>S</i>. Vertices colored white or gray are in <i>V-S</i>. White vertices have
-not yet been discovered and gray vertices are in the priority queue.
-By default, the algorithm will allocate an array to store a color
-marker for each vertex in the graph. You can provide your own storage
-and access for colors with the <tt>color_map()</tt> parameter.
-</P>
-<p>
-The following is the pseudo-code for Dijkstra's single-source shortest
-paths algorithm. <i>w</i> is the edge weight, <i>d</i> is the distance label,
-and <i>p</i> is the predecessor of each vertex which is used to encode
-the shortest paths tree. <i>Q</i> is a priority queue that supports the
-DECREASE-KEY operation.  The visitor event points for the algorithm are
-indicated by the labels on the right.

-  is invoked on each vertex in the graph before the start of the
-  algorithm.
-<li><b><tt>vis.examine_vertex(u, g)</tt></b>
-  is invoked on a vertex as it is removed from the priority queue
-  and added to set <i>S</i>. At this point we know that <i>(p[u],u)</i>
-  is a shortest-paths tree edge so
-  <i>d[u] = delta(s,u) = d[p[u]] + w(p[u],u)</i>. Also, the distances
-  of the examined vertices is monotonically increasing
-  <i>d[u<sub>1</sub>] <= d[u<sub>2</sub>] <= d[u<sub>n</sub>]</i>.
-<li><b><tt>vis.examine_edge(e, g)</tt></b>
-  is invoked on each out-edge of a vertex immediately after it has
-  been added to set <i>S</i>.
-<li><b><tt>vis.edge_relaxed(e, g)</tt></b>
-  is invoked on edge <i>(u,v)</i> if <i>d[u] + w(u,v) < d[v]</i>.
-  The edge <i>(u,v)</i> that participated in the last

-<li><b><tt>vis.discover_vertex(v, g)</tt></b>
-  is invoked on vertex <i>v</i> when the edge
-  <i>(u,v)</i> is examined and <i>v</i> is WHITE. Since
-  a vertex is colored GRAY when it is discovered,
-  each reachable vertex is discovered exactly once. This
-  is also when the vertex is inserted into the priority queue.
-<li><b><tt>vis.edge_not_relaxed(e, g)</tt></b>
-  is invoked if the edge is not relaxed (see above).
-<li><b><tt>vis.finish_vertex(u, g)</tt></b>
-   is invoked on a vertex after all of its out edges have
-  been examined.

-
-<H3>See also</H3> <a href="dijkstra_shortest_paths_no_color_map.html">dijkstra_shortest_paths_no_color_map</a> for a version of Dijkstra's shortest path that does not use a color map.
-
-<H3>Notes</H3>
-
-<a name="1">[1]</a>
-The algorithm used here saves a little space by not putting all <i>V -
-S</i> vertices in the priority queue at once, but instead only those
-vertices in <i>V - S</i> that are discovered and therefore have a
-distance less than infinity.
-
-<p><a name="2">[2]</a>
-  Since the visitor parameter is passed by value, if your visitor
-  contains state then any changes to the state during the algorithm
-  will be made to a copy of the visitor object, not the visitor object
-  passed in. Therefore you may want the visitor to hold this state by
-  pointer or reference.
