[SVN r50232]
2008-12-10 15:56:02 +00:00
Andrew Sutton a6daa83472 Added tests for out edge and adjacency components under add_vertex.
For some reason, adjacency_iterators seem to remain valid if no operations
on other graph types are executed prior to their use, which is completely
at odds with what I would expect.


[SVN r50231]
2008-12-10 15:46:05 +00:00
Andrew Sutton 7f9306dec9 Added a small test framework for experimenting with invalidating iterators
and descriptors. Not part of the test suite.


[SVN r50230]
2008-12-10 14:28:25 +00:00
Andrew Sutton 9ad0c6a23c Fixed #1622. A viable solution relies on the fact that incident edges in a
loop are stored adjacently in the out edge list of the vertex. A simple
modification of the global edge erasing loop for undirected graphs will
skip the next iterator if both the current and next contain the same iterator.


[SVN r50206]

John Maddock a9a49a55b7 Merge fixes from Trunk.
Fixes #2392.

Change includes of <cmath> to <boost/config/no_tr1/config.hpp>.

Previously if Boost.TR1 was in the include path then including <cmath> pulls in all the new TR1 math functions, which in turn also requires linking to an external library. With auto-linking support this requires that library to have been built and be present in the library search path, even if the actual library under use is header only.

Douglas Gregor 23b3545c8d Overall: Second, more complete and better tested version of bundled properties.
The ->* syntax has been removed. Instead, one may use the member pointer as
the key for the standard get/put functions of property maps. This makes
graph adaptors work with bundled properties (automagically). Also added
support for bundled properties in adjacency_matrix.

index.htm: Announce the addition of bundled properties.

boost/graph/adjacency_list.hpp: Updated to support get/put for bundled
properties.

boost/graph/adjacency_matrix.hpp: Added support for bundled properties.
Suppressed some warnings and fixed a minor bug in add_edge(u, v, ep, g).

boost/graph/properties.hpp: Added property_map specialization for bundled
properties.

libs/graph/doc/*.html: Document uses of bundled properties and direct anyone
not using a broken compiler to bundled properties instead of property lists.

libs/graph/test/bundled_properties.cpp: Test both adjacency_list and
adjacency_matrix, along with filtered_graph. Makes sure all of the bundled
properties operations work.

"Reasonable copying fee" is whatever you can justify on the basis of
media cost, duplication charges, time of people involved, and so
on. (You will not be required to justify it to the Copyright Holder,
but only to the computing community at large as a market that must
bear the fee.)
"Freely Available" means that no fee is charged for the item itself,
though there may be fees involved in handling the item. It also means
that recipients of the item may redistribute it under the same
conditions they received it.
1. You may make and give away verbatim copies of the source form of
the Standard Version of this Package without restriction, provided
that you duplicate all of the original copyright notices and

provided that you insert a prominent notice in each changed file
stating how and when you changed that file, and provided that you do
at least ONE of the following:
a. place your modifications in the Public Domain or otherwise make
them Freely Available, such as by posting said modifications to Usenet
or an equivalent medium, or placing the modifications on a major
archive site such as uunet.uu.net, or by allowing the Copyright Holder
to include your modifications in the Standard Version of the Package.
b. use the modified Package only within your corporation or organization.
c. rename any non-standard types and functions so the names do not
conflict with Standard Vibrary, which must also be provided, and
provide a separate documentation for each non-standard type of function
that clearly documents how it differs from the Standard Version.
d. make other distribution arrangements with the Copyright Holder.
4. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this
Package. You may not charge a fee for this Package itself. However,

<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>
<a href="http://www.sgi.com/tech/stl/UnaryFunction.html">Unary
Function</a> (must take a single argument -- a graph vertex -- and
return a cost value) and <a
href="../../utility/CopyConstructible.html">Copy Constructible</a>
(copying a heuristic should be a lightweight operation).

<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.

</td></tr>
</tbody></table>
</p><h3>Models</h3>
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.
</ul>

To implement a model of the <tt>DijkstraVisitor</tt> concept in Python,
create a new class that derives from the <tt>DijkstraVisitor</tt> type of
the graph, which will be
named <tt><i>GraphType</i>.DijkstraVisitor</tt>. The events and syntax are
the same as with visitors in C++. Here is an example for the
Python <tt>bgl.Graph</tt> graph type:
<pre>
class count_tree_edges_dijkstra_visitor(bgl.Graph.DijkstraVisitor):
def __init__(self, name_map):
bgl.Graph.DijkstraVisitor.__init__(self)
self.name_map = name_map

(u, v) = (g.source(e), g.target(e))

print self.name_map[u],
print " -> ",

<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;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)
);
// planar_embedding can now be passed to any function expecting a model
// of PlanarEmbedding.
</pre>

</PRE>
<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> 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>
This implementation of A* is based on an OPEN/CLOSED list formulation
of the algorithm. 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.
</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.

</blockquote>
UTIL/OUT: <tt>color_map(ColorMap c_map)</tt>
<blockquote>
This is used during the execution of the algorithm to mark the
vertices, indicating whether they are on the OPEN or CLOSED lists.
The vertices start out white and become gray when they are inserted
into the OPEN list. They then turn black when they are examined and
placed on the CLOSED list. At the end of the algorithm, vertices
reachable from the source vertex will have been colored black. All
other vertices will still be white. The type <tt>ColorMap</tt> must

</blockquote>
IN: <tt>distance_compare(CompareFunction cmp)</tt>

is closer to the start vertex, and to compare <i>f</i>-values to
determine which vertex on the OPEN list to examine next. The

the <i>f</i>-value of a vertex. The <tt>CombineFunction</tt> type
must be a model of <a

Function</tt></a>. Both argument types of the binary function must
match the value type of the <tt>DistanceMap</tt> property map (which
is the same as that of the <tt>WeightMap</tt> and <tt>CostMap</tt>
property maps). The result type must be the same type as the
distance value type.<br>

<H3>Complexity</H3>
<P>
The time complexity is <i>O((E + V) log V)</i>.
<h3>Visitor Event Points</h3>
<ul>
<li><b><tt>vis.initialize_vertex(u, g)</tt></b>
is invoked on each vertex in the graph before the start of the
algorithm.
<li><b><tt>vis.discover_vertex(v, g)</tt></b>
is invoked when a vertex is first discovered and is added to the
OPEN list.
<li><b><tt>vis.examine_vertex(u, g)</tt></b>
is invoked when a vertex is popped from
the queue (i.e., it has the lowest cost on the OPEN list).
<li><b><tt>vis.examine_edge(e, g)</tt></b>
is invoked on each out-edge of a vertex immediately after it is
examined.
<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) &lt; d[v]</i>.
<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.black_target(e, g)</tt></b>
is invoked when a vertex that is on the CLOSED list is
"rediscovered" via a more efficient path, and is re-added to the
OPEN list.
<li><b><tt>vis.finish_vertex(u, g)</tt></b>
is invoked on a vertex when it is added to the CLOSED list, which
happens after all of its out edges have been examined.
</ul>
<H3>Example</H3>
<P>
See <a href="../example/astar-cities.cpp">
<TT>example/astar-cities.cpp</TT></a> for an example of
using A* search.
<H3>Notes</H3>
<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.

<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>adjacenty_list</tt> with <tt>VertexList=listS</tt> does
not have an internal <tt>vertex_index</tt> property.<br>

<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:
<p><img src="figs/central_point_dominance.gif">

<P>
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>].

<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>
A graph is <a href="./planar_graphs.html#planar"><i>planar</i></a> if it can
be drawn in two-dimensional space without any of its edges crossing. Such a
drawing of a planar graph is called a
<a href="./planar_graphs.html#plane_drawing"><i>plane drawing</i></a>. Each
plane drawing belongs to an equivalence class called a <i>planar embedding</i>
<a href="#1">[1]</a> that is defined by the clockwise ordering of adjacent
edges around each vertex in the graph. A planar embedding is a convenient
intermediate representation of an actual drawing of a planar graph, and many
planar graph drawing algorithms are formulated as functions mapping a planar
embedding to a plane drawing.

<p>
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>
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>.

<H3>Complexity</H3>
Assuming that both the vertex index and edge index supplied take time
<i>O(1)</i> to return an index and there are <i>O(n)</i>
total self-loops and parallel edges in the graph, most combinations of
arguments given to
<tt>boyer_myrvold_planarity_test</tt> result in an algorithm that runs in time
<i>O(n)</i> for a graph with <i>n</i> vertices and <i>m</i> edges. The only
exception is when Kuratowski subgraph isolation is requested for a dense graph
(a graph with <i>n = o(m)</i>) - the running time will be <i>O(n+m)</i>

<h3>Notes</h3>
<p><a name="1">[1] A planar embedding is also called a <i>combinatorial
embedding</i>.
<p><a name="2">[2] The algorithm can still be made to run in time <i>O(n)</i>
for this case, if needed. <a href="planar_graphs.html#EulersFormula">Euler's
formula</a> implies that a planar graph with <i>n</i> vertices can have no more
than <i>3n - 6</i> edges, which means that any non-planar graph on <i>n</i>
vertices has a subgraph of only <i>3n - 5</i> edges that contains a Kuratowski
subgraph. So, if you need to find a Kuratowski subgraph of a graph with more
than <i>3n - 5</i> edges in time <i>O(n)</i>, you can create a subgraph of the
original graph consisting of any arbitrary <i>3n - 5</i> edges and pass that
graph to <tt>boyer_myrvold_planarity_test</tt>.

<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
Flow Algorithms</A> for a description of maximum flow. The calculated
maximum flow will be the return value of the function. The function
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>
<P><B>Requirements:</B><BR>The directed graph <I>G=(V,E)</I> that
represents the network must include a 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) -&gt; (v,u)</I> for all <I>(u,v)</I> in <I>E</I>.
</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 substracting 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 substracting 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>

<title>Bundled Properties</title>
</head>
<body BGCOLOR="#ffffff" LINK="#0000ee" TEXT="#000000" VLINK="#551a8b"
ALINK="#ff0000">
<IMG SRC="../../../boost.png"
ALT="C++ Boost" width="277" height="86"/>
<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>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_length_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>With bundled properties, we can directly use the
<code>City</code> and <code>Highway</code> structures:</p>
<pre>
typedef boost::adjacency_list&lt;
boost::listS, boost::vecS, boost::bidirectionalS,
City, Highway&gt; Map;
</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>
<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, int Highway::*&gt;::type</code>
or <code>property_map&lt;Map, int 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>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
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

<a name="models"></a><h2>Models</h2>
<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
to be used with most of the BGL algorithms. In particular, it
models the following specific graph concepts:</p>
<ul>
<li><a href="Graph.html">Graph</a></li>
<li><a href="IncidenceGraph.html">IncidenceGraph</a></li>
<li><a href="AdjacencyGraph.html">AdjacencyGraph</a></li>

<li><a href="PropertyGraph.html">PropertyGraph</a></li>
</ul>
<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
be attached to its vertices, edges, or to the graph itself by way
of its <a href="#template-parms">template parameters</a>. These
properties may be accessed via
the <a href="#property-access">member</a>
and <a href="#property-map-accessors">non-member</a> property
access functions, using the <a href="bundles.html">bundled
properties</a> scheme.</p>
<p>The CSR graph provides two kinds of built-in
properties: <tt>vertex_index</tt>, which maps from vertices to
values in <tt>[0, n)</tt> and <tt>edge_index</tt>, which maps
from edges to values in <tt>[0, m)</tt>, where <tt>n</tt>
and <tt>m</tt> are the number of vertices and edges in the graph,
respectively. </p>

class to store a simple Web graph. In this web graph the vertices
represent web pages and the edges represent links from one web
page to another. With each web page we want to associate a URL, so
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>
<pre>
class WebPage
{
public:
std::string url;
};
// ...
typedef compressed_sparse_row_graph&lt;directedS, WebPage&gt; WebGraph;
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,
and display the edges for the user.</p>
<pre>
// Set the URLs of each vertex
int index = 0;
BGL_FORALL_VERTICES(v, g, WebGraph)
g[v].url = urls[index++];

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.
</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.

The time complexity is <i>O(V log V)</i>.
<h3>Visitor Event Points</h3>
<ul>
<li><b><tt>vis.initialize_vertex(u, g)</tt></b>
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
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.
</ul>
<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 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>If you want the possibility of generating parallel edges and don't
care about sorted order, use the <a
href="erdos_renyi_generator.html"><tt>erdos_renyi_iterator</tt></a>.</p>
