alpar@40: \brief Graph structures implemented in LEMON.
alpar@40: 
alpar@209: The implementation of combinatorial algorithms heavily relies on
alpar@209: efficient graph implementations. LEMON offers data structures which are
alpar@209: planned to be easily used in an experimental phase of implementation studies,
alpar@209: and thereafter the program code can be made efficient by small modifications.
alpar@40: 
alpar@40: The most efficient implementation of diverse applications require the
alpar@40: usage of different physical graph implementations. These differences
alpar@40: appear in the size of graph we require to handle, memory or time usage
alpar@40: limitations or in the set of operations through which the graph can be
alpar@40: accessed.  LEMON provides several physical graph structures to meet
alpar@40: the diverging requirements of the possible users.  In order to save on
alpar@40: running time or on memory usage, some structures may fail to provide
kpeter@83: some graph features like arc/edge or node deletion.
alpar@40: 
alpar@209: Alteration of standard containers need a very limited number of
alpar@209: operations, these together satisfy the everyday requirements.
alpar@209: In the case of graph structures, different operations are needed which do
alpar@209: not alter the physical graph, but gives another view. If some nodes or
kpeter@83: arcs have to be hidden or the reverse oriented graph have to be used, then
alpar@209: this is the case. It also may happen that in a flow implementation
alpar@209: the residual graph can be accessed by another algorithm, or a node-set
alpar@209: is to be shrunk for another algorithm.
alpar@209: LEMON also provides a variety of graphs for these requirements called
alpar@209: \ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only
alpar@209: in conjunction with other graph representations.
alpar@40: 
alpar@40: You are free to use the graph structure that fit your requirements
alpar@40: the best, most graph algorithms and auxiliary data structures can be used
kpeter@314: with any graph structure.

alpar@40: \defgroup map_adaptors Map Adaptors
alpar@40: \ingroup maps
alpar@40: \brief Tools to create new maps from existing ones
alpar@40: 
kpeter@50: This group describes map adaptors that are used to create "implicit"
kpeter@50: maps from other maps.
alpar@40: 
kpeter@83: Most of them are \ref lemon::concepts::ReadMap "read-only maps".
kpeter@83: They can make arithmetic and logical operations between one or two maps
kpeter@83: (negation, shifting, addition, multiplication, logical 'and', 'or',
kpeter@83: 'not' etc.) or e.g. convert a map to another one of different Value type.
alpar@40: 
kpeter@50: The typical usage of this classes is passing implicit maps to
alpar@40: algorithms.  If a function type algorithm is called then the function
alpar@40: type map adaptors can be used comfortable. For example let's see the
kpeter@314: usage of map adaptors with the \c graphToEps() function.
alpar@40: \code
alpar@40:   Color nodeColor(int deg) {
alpar@40:     if (deg >= 2) {
alpar@40:       return Color(0.5, 0.0, 0.5);
alpar@40:     } else if (deg == 1) {
alpar@40:       return Color(1.0, 0.5, 1.0);
alpar@40:     } else {
alpar@40:       return Color(0.0, 0.0, 0.0);
alpar@40:     }
alpar@40:   }
alpar@209: 
kpeter@83:   Digraph::NodeMap<int> degree_map(graph);
alpar@209: 
kpeter@314:   graphToEps(graph, "graph.eps")
alpar@40:     .coords(coords).scaleToA4().undirected()
kpeter@83:     .nodeColors(composeMap(functorToMap(nodeColor), degree_map))
alpar@40:     .run();
alpar@209: \endcode
kpeter@83: The \c functorToMap() function makes an \c int to \c Color map from the
kpeter@314: \c nodeColor() function. The \c composeMap() compose the \c degree_map
kpeter@83: and the previously created map. The composed map is a proper function to
kpeter@83: get the color of each node.
alpar@40: 
alpar@40: The usage with class type algorithms is little bit harder. In this
alpar@40: case the function type map adaptors can not be used, because the
kpeter@50: function map adaptors give back temporary objects.
alpar@40: \code
kpeter@83:   Digraph graph;
kpeter@83: 
kpeter@83:   typedef Digraph::ArcMap<double> DoubleArcMap;
kpeter@83:   DoubleArcMap length(graph);
kpeter@83:   DoubleArcMap speed(graph);
kpeter@83: 
kpeter@83:   typedef DivMap<DoubleArcMap, DoubleArcMap> TimeMap;
alpar@40:   TimeMap time(length, speed);
alpar@209: 
kpeter@83:   Dijkstra<Digraph, TimeMap> dijkstra(graph, time);
alpar@40:   dijkstra.run(source, target);
alpar@40: \endcode
kpeter@83: We have a length map and a maximum speed map on the arcs of a digraph.
kpeter@83: The minimum time to pass the arc can be calculated as the division of
kpeter@83: the two maps which can be done implicitly with the \c DivMap template
alpar@40: class. We use the implicit minimum time map as the length map of the
alpar@40: \c Dijkstra algorithm.

alpar@40: 
kpeter@50: The maximum flow problem is to find a flow between a single source and

alpar@40: directed graph, an \f$c_a:A\rightarrow\mathbf{R}^+_0\f$ capacity
alpar@40: function and given \f$s, t \in V\f$ source and target node. The
kpeter@50: maximum flow is the \f$f_a\f$ solution of the next optimization problem:
alpar@40: 
alpar@40: \f[ 0 \le f_a \le c_a \f]
alpar@210: \f[ \sum_{v\in\delta^{-}(u)}f_{vu}=\sum_{v\in\delta^{+}(u)}f_{uv}

alpar@40: \f[ \max \sum_{v\in\delta^{+}(s)}f_{uv} - \sum_{v\in\delta^{-}(s)}f_{vu}\f]
alpar@40:
