10\brief Graph structures implemented in LEMON.
11
12The implementation of combinatorial algorithms heavily relies on
13efficient graph implementations. LEMON offers data structures which are
14planned to be easily used in an experimental phase of implementation studies,
15and thereafter the program code can be made efficient by small modifications.
16
17The most efficient implementation of diverse applications require the
18usage of different physical graph implementations. These differences
19appear in the size of graph we require to handle, memory or time usage
20limitations or in the set of operations through which the graph can be
21accessed.  LEMON provides several physical graph structures to meet
22the diverging requirements of the possible users.  In order to save on
23running time or on memory usage, some structures may fail to provide
24some graph features like edge or node deletion.
25
26Alteration of standard containers need a very limited number of
27operations, these together satisfy the everyday requirements.
28In the case of graph structures, different operations are needed which do
29not alter the physical graph, but gives another view. If some nodes or
30edges have to be hidden or the reverse oriented graph have to be used, then
31this is the case. It also may happen that in a flow implementation
32the residual graph can be accessed by another algorithm, or a node-set
33is to be shrunk for another algorithm.
34LEMON also provides a variety of graphs for these requirements called
35\ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only
36in conjunction with other graph representation.
37
38You are free to use the graph structure that fit your requirements
39the best, most graph algorithms and auxiliary data structures can be used
40with any graph structures.

80make arithmetic operations between one or two maps (negation, scaling,
81addition, multiplication etc.) or e.g. convert a map to another one

288
289The purpose of the classes in this group is fourfold.
290 
291- These classes contain the documentations of the concepts. In order
292  to avoid document multiplications, an implementation of a concept
293  simply refers to the corresponding concept class.
294
295- These classes declare every functions, <tt>typedef<tt>s etc. an
296  implementation of the concepts should provide, however completely
297  without implementations and real data structures behind the
298  interface. On the other hand they should provide nothing else. All
299  the algorithms working on a data structure meeting a certain concept
300  should compile with these classes. (Though it will not run properly,
301  of course.) In this way it is easily to check if an algorithm
302  doesn't use any extra feature of a certain implementation.
303
304- The concept descriptor classes also provide a <em>checker class<em>
305  that makes it possible check whether a certain implementation of a
306  concept indeed provides all the required features.
307
308- Finally, They can serve as a skeleton of a new implementation of a concept.
