@defgroup graphs Graph Structures

\brief Graph structures implemented in LEMON.

The implementation of combinatorial algorithms heavily relies on 
efficient graph implementations. LEMON offers data structures which are 
planned to be easily used in an experimental phase of implementation studies, 
and thereafter the program code can be made efficient by small modifications. 

The most efficient implementation of diverse applications require the usage of different physical graph implementations. These differences appear in the size of 
graph we require to handle, memory or time usage limitations or in 
the set of operations through which the graph can be accessed. 
LEMON provides several physical graph structures to meet the 
diverging requirements of the possible users. 
In order to save on running time or on memory usage, some structures may 
fail to provide some graph features like edge or node deletion.

Alteration of standard containers need a very limited number of 
operations, these together satisfy the everyday requirements. 
In the case of graph strutures, different operations are needed which do 
not alter the physical graph, but gives another view. If some nodes or 
edges have to be hidden or the reverse oriented graph have to be used, then 
this is the case. It also may happen that in a flow implemenation 
the residual graph can be accessed by another algorithm, or a node-set 
is to be shrunk for another algorithm. 
LEMON also provides a variety of graphs for these requirements called 
\ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only 
in conjunction with other graph representation. 

You are free to use the graph structure that fit your requirements
the best, most graph algorithms and auxiliary data structures can be used
with any graph structures.

Map adaptors are used to create "implicit" maps from other maps.

Most of them are \ref lemon::concept::ReadMap "ReadMap"s. They can
make arithmetic oprerations between one or two maps (negation, scalig,
addition, multiplication etc.) or e.g. convert a map to another one
of different Value type.
