As initial value of a new map expression with ()+-/* operators can be given. These operators work on numbers, or on maps. If maps are given, then the new value for a given graph element will be calculated using the value from the given maps that belong to that graph element.

10 \brief Graph structures implemented in LEMON.
12 The implementation of combinatorial algorithms heavily relies on
13 efficient graph implementations. LEMON offers data structures which are
14 planned to be easily used in an experimental phase of implementation studies,
15 and thereafter the program code can be made efficient by small modifications.
17 The most efficient implementation of diverse applications require the usage of different physical graph implementations. These differences appear in the size of
18 graph we require to handle, memory or time usage limitations or in
19 the set of operations through which the graph can be accessed.
20 LEMON provides several physical graph structures to meet the
21 diverging requirements of the possible users.
22 In order to save on running time or on memory usage, some structures may
23 fail to provide some graph features like edge or node deletion.
25 Alteration of standard containers need a very limited number of
26 operations, these together satisfy the everyday requirements.
27 In the case of graph strutures, different operations are needed which do
28 not alter the physical graph, but gives an other view. If some nodes or
29 edges have to be hidden or the reverse oriented graph have to be used, then
30 this is the case. It also may happen that in a flow implemenation
31 the residual graph can be accessed by an other algorithm, or a node-set
32 is to be shrunk for an other algorithm.
33 LEMON also provides a variety of graphs for these requirements called
34 \ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only
35 in conjunction with other graph representation.
37 You are free to use the graph structure that fit your requirements
38 the best, most graph algorithms and auxiliary data structures can be used
39 with any graph structures.
45 \brief Some special purpose map to make life easier.
47 LEMON provides several special maps that e.g. combine
48 new maps from existing ones.

63 \defgroup map_adaptors Map Adaptors
65 \brief Tools to create new maps from existing ones
67 Map adaptors are used to create "implicit" maps from other maps.
69 Most of them are \ref lemon::concept::ReadMap "ReadMap"s. They can
70 make arithmetic oprerations between one or two maps (negation, scalig,
71 addition, multiplication etc.) or e.g. convert a map to another one
72 of different Value type.
