+
+===================
+
+A generic interface for traversing graphs, using C++ templates.
+
+The full documentation is available on [boost.org](http://www.boost.org/doc/libs/release/libs/graph/doc/index.html).
+
+## Support, bugs and feature requests ##
+
+Bugs and feature requests can be reported through the [Github issue page](https://github.com/boostorg/graph/issues).
+
+See also:
+
+* [Current open issues](https://github.com/boostorg/graph/issues)

+
+Clone the whole boost project, which includes the individual Boost projects as submodules ([see boost+git doc](https://github.com/boostorg/boost/wiki/Getting-Started)):
+
+    git clone https://github.com/boostorg/boost
+    cd boost
+    git submodule update --init
+
+The Boost Graph Library is located in `libs/graph/`.
+
+Boost Graph Library is mostly made of headers but also contains some compiled components. Here are the build commands:
+
+    ./bootstrap.sh            <- compile b2
+    ./b2 headers              <- just installs headers
+    ./b2                      <- build compiled components
+
+**Note:** The Boost Graph Library cannot currently be built outside of Boost itself.
+
+### 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:
+
+    ../../../b2                        <- run all tests
+    ../../../b2 cycle_canceling_test   <- single test
+
+You can also check the [regression tests reports](http://beta.boost.org/development/tests/develop/developer/graph.html).

+<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>.
+
+<h3>Refinement of</h3>

+Function</a> (must take a single argument -- a graph vertex -- and

+<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.

+<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.
+</ul>

+<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.

+<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.

+<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

+<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.

+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.

+
+<p>This algorithm&nbsp;[<a href="bibliography.html#brandes01">54</a>]
+computes the <em>betweenness centrality</em>&nbsp;[<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
+vertex <em>s</em> to vertex <em>t</em> and <img src="figs/sigma_stv.gif">
+is the number of shortest paths from vertex <em>s</em> to vertex
+<em>t</em> that pass through vertex <em>v</em>.
+
+<!-- \sum_{s \neq v \neq t}\frac{\sigma_{st}(v)}{\sigma_{st}} -->
+
+<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
+of this algorithm can compute either the vertex or edge centrality (or
+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
+point in the graph: it will be 0 for complete graphs and
+1 for "wheel" graphs (in which there is a central vertex that all
+paths include; see <a href="#Fig1">Fig. 1</a>). Let <img src="figs/v_star.gif"> be the vertex with the largest relative betweenness centrality; then, the central point dominance is defined as:

+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>].

+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>
+If the graph is not planar, a set of edges that forms a Kuratowski subgraph in
+the original graph can be produced. This set of edges can be passed to the
+function <tt><a href="is_kuratowski_subgraph.html">is_kuratowski_subgraph</a>
+</tt> to verify that they can be contracted into a <i>K<sub>5</sub></i> or
+<i>K<sub>3,3</sub></i>. <tt>boyer_myrvold_planarity_test</tt> chooses the set
+of edges forming the Kuratowski subgraph in such a way that the contraction to
+a <i>K<sub>5</sub></i> or <i>K<sub>3,3</sub></i> can be done by a simple
+deterministic process which is described in the documentation to
+<tt>is_kuratowski_subgraph</tt>.

+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>

+<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>

+    <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

+        <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>

+        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

+    </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

+    we initially create a <tt>WebPage</tt> class that stores the
+    URL. Then we can create our graph type by providing
+    <tt>WebPage</tt> as a parameter to the
+    <tt>compressed_sparse_row_graph</tt> class template.</p>

+WebGraph g(&the_edges[0], &the_edges[0] + sizeof(the_edges)/sizeof(E), 6);
+    </pre>
+
+    <p>We can then set the properties on the vertices of the graph
+    using the <a href="bundles.html">bundled properties</a> syntax,

+</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#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>
+	<tt>dijkstra_shortest_paths_no_color_map</tt> differs from the original <tt>dijkstra_shortest_paths</tt> algorithm by not using a color map to identify vertices as discovered or undiscovered.  Instead, this is done with the distance map: a vertex <i>u</i> such that <i>distance_compare(distance_map[u], distance_infinity) == false</i> is considered to be undiscovered.  Note that this means that edges with infinite weight will not work correctly in this algorithm.
+</P>
+
+<P>
+There are two main options for obtaining output from the
+<tt>dijkstra_shortest_paths_no_color_map()</tt> function. If you provide a
+distance property map through the <tt>distance_map()</tt> parameter
+then the shortest distance from the start 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 <a href="#4">[4]</a>.</P>
+
+<P>
+Dijkstra's algorithm finds all the shortest paths from the source
+vertex to every other vertex by iteratively &quot;growing&quot; 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 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.

+<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
+  relaxation for vertex <i>v</i> is an edge in the shortest paths tree.
+<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> has not yet been discovered (i.e. its distance was infinity before relaxation was attempted on the edge).  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>Example</H3>
+
+<P>
+See <a href="../example/dijkstra-no-color-map-example.cpp">
+<TT>example/dijkstra-no-color-map-example.cpp</TT></a> for an example of using Dijkstra's algorithm.
+
+<H3>See also</H3> <a href="dijkstra_shortest_paths.html">dijkstra_shortest_paths</a> for a version of Dijkstra's shortest path that uses a color map.
+
+<H3>Notes</H3>
+
+<p>Based on the documentation for <a href="dijkstra_shortest_paths.html">dijkstra_shortest_paths</a>.
+
+<p><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.
+
+<p><a name="3">[3]</a>
+  The algorithm will not work correctly if any of the edge weights are equal to infinity since the infinite distance value is used to determine if a vertex has been discovered.
+
+<p><a name="4">[4]</a>
+  Calls to the visitor events occur in the same order as <tt>dijkstra_shortest_paths</tt> (i.e. <i>discover_vertex(u)</i> will always be called after <i>examine_vertex(u)</i> for an undiscovered vertex <i>u</i>).  However, the vertices of the graph given to <i>dijkstra_shortest_paths_no_color_map</i> will <b>not</b> necessarily be visited in the same order as <i>dijkstra_shortest_paths</i>.

+
+  <p>This is a class that provides disjoint set operations with <i>union by
+  rank</i> and <i>path compression</i>. A disjoint-sets data structure
+  maintains a collection <i>S = {S<sub>1</sub>, S<sub>2</sub>, ...,
+  S<sub>k</sub>}</i> of disjoint sets. Each set is identified by a
+  <i>representative</i> which is some member of of the set. Sets are
+  represented by rooted trees which are encoded in the <tt>Parent</tt>
+  property map. Two heuristics: "union by rank" and "path compression" are
+  used to speed up the operations&nbsp;[<a href=
+  "./disjoint_sets_biblio.html#tarjan83:_data_struct_network_algo">1</a>, <a href=

+
+  <p>This class manages the storage for the rank and parent properties

+  The rank and parent properties are initialized during construction so the

+
+This is an <a href="./EventVisitor.html">EventVisitor</a> that records
+the predecessor (or parent) edge of a vertex in a property
+map. This is particularly useful in graph search algorithms where
+recording the predecessors is an efficient way to encode the search
+tree that was traversed during the search. The edge predecessor recorder is
+typically used with the <tt>on_tree_edge</tt> or
+<tt>on_relax_edge</tt> events and cannot be used with vertex events.  This
+visitor is meant to be used instead of <a
+href="predecessor_recorder.html"><tt>predecessor_recorder</tt></a> when a
+graph has parallel edges and it is necessary to know which incoming edge a
+search algorithm
+used to get to a particular vertex.
+
+<p>
+<tt>edge_predecessor_recorder</tt> can be used with graph algorithms by
+wrapping it with an algorithm-specific adaptor, such as <a
+href="./bfs_visitor.html"><tt>bfs_visitor</tt></a> and <a
+href="./dfs_visitor.html"><tt>dfs_visitor</tt></a>. Also, this event
+visitor can be combined with other event visitors using
+<tt>std::pair</tt> to form an EventVisitorList.
+
+<p>
+Algorithms such as Dijkstra's and breadth-first search will not assign
+a predecessor edge to the source vertex (which is the root of the search
+tree). It is often useful to initialize the source vertex's
+predecessor to a special value, thereby identifying the root vertex.
+When using an algorithm like
+depth-first search that creates a forest (multiple search trees) it
+is useful to do the same for every vertex. This
+way all the root nodes can be distinguished.

+<p> This class template implements a generator for Erd&ouml;s-Renyi
+graphs, suitable for initializing an <a
+href="adjacency_list.html"><tt>adjacency_list</tt></a> or other graph
+structure with iterator-based initialization. An Erd&ouml;s-Renyi
+graph <em>G = (n, p)</em> is a graph with <em>n</em> vertices
+that. The probability of having an edge <em>(u, v)</em> in <em>G</em>
+is <em>p</em> for any vertices <em>u</em> and <em>v</em>. Typically,
+there are no self-loops, but the generator can optionally introduce
+self-loops with probability <em>p</em>. This generator will not
+produce any parallel edges and will produce edges in sorted order (as
+required by, e.g., the <a
+href="compressed_sparse_row.html"><tt>compressed_sparse_row_graph</tt></a>).</p>
+
+<p>Erd&ouml;s-Renyi graphs typically exhibit very little
+structure. For this reason, they are rarely useful in modeling
+real-world problems. However, they are often used when determining
+the theoretical complexity of complex graph algorithms.</p>

+<P>
+The BGL defines several exception classes for reporting errors from
+BGL algorithms. Many of the BGL algorithms place certain requirements
+on the input graph. If these requirements are not met then the
+algorithm can not successfully complete, and instead throws the
+appropriate exception.

 <h1>Frequently Asked Questions</h1>

 <ol>

+<li>
+How do I perform an early exit from an algorithm such as BFS?<br>
+
+<p>
+Create a visitor that throws an exception when you want to cut off the
+search, then put your call to <tt>breadth_first_search</tt> inside of
+an appropriate try/catch block. This strikes many programmers as a
+misuse of exceptions, however, much thought was put into the decision
+to have exceptions has the preferred way to exit early. See boost
+email discussions for more details.
+</p>
+
+<li>
+Why is the visitor parameter passed by value rather than reference
+in the various BGL algorithms?<br>
+
+<p>
+One of the usage scenarios that we wanted to support with the
+algorithms was creating visitor objects on the fly, within the
+argument list of the call to the graph algorithm. In this situation,
+the visitor object is a temporary object. Now there is a truly
+unfortunate rule in the C++ standard that says a temporary cannot be
+bound to a non-const reference parameter.  So we had to decide whether
+we wanted to support this kind of usage and call-by-value, or not and
+call-by-reference. We chose call-by-value, following in the footsteps
+of the STL (which passes functors by value).  The disadvantage of this
+decision is that if your visitor contains state and changes that state
+during the algorithm, the change 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>
+
+<li>Why does the BGL interface use friend functions (or free functions)
+  instead of member functions?<br>
+<p>
+For the most part, the differences between member functions and free
+functions are syntactic, and not very important, though people can get
+religious about them. However, we had one technical reason for
+favoring free functions. A programmer can overload a free function for
+a type coming from a 3rd party without modifying the source
+code/definition of that type. There are several uses of this in the
+BGL. For example, Stanford GraphBase and LEDA graphs can both be used
+in BGL algorithms because of overloads in <tt>stanford_graph.hpp</tt>
+and <tt>leda_graph.hpp</tt>. One can even use
+<tt>std::vector&lt;std::list&gt;</tt> as a graph due to the overloads
+in <tt>vector_as_graph.hpp</tt>.
+</p>
+<p>
+Of course, there is a way to adapt 3rd party classes into an interface
+with member functions. You create an adaptor class. However, the
+disadvantage of an adaptor class (compared to overloaded functions) is
+that one has to physically wrap and unwrap the objects as they go
+into/out of BGL algorithms. So the overloaded function route is more
+convenient.  Granted, this is not a huge difference, but since there
+weren't other strong reasons, it was enough for us to choose free
+functions.
+</p>
+
+<p>
+Our religious reason for choosing free functions is to send the message
+that BGL is a generic library, and not a traditional object-oriented
+library. OO was hip in the 80s and 90s, but its time we moved beyond!
