27 | \brief Graph structures implemented in LEMON. |
---|
28 | |
---|
29 | The implementation of combinatorial algorithms heavily relies on |
---|
30 | efficient graph implementations. LEMON offers data structures which are |
---|
31 | planned to be easily used in an experimental phase of implementation studies, |
---|
32 | and thereafter the program code can be made efficient by small modifications. |
---|
33 | |
---|
34 | The most efficient implementation of diverse applications require the |
---|
35 | usage of different physical graph implementations. These differences |
---|
36 | appear in the size of graph we require to handle, memory or time usage |
---|
37 | limitations or in the set of operations through which the graph can be |
---|
38 | accessed. LEMON provides several physical graph structures to meet |
---|
39 | the diverging requirements of the possible users. In order to save on |
---|
40 | running time or on memory usage, some structures may fail to provide |
---|
41 | some graph features like edge or node deletion. |
---|
42 | |
---|
43 | Alteration of standard containers need a very limited number of |
---|
44 | operations, these together satisfy the everyday requirements. |
---|
45 | In the case of graph structures, different operations are needed which do |
---|
46 | not alter the physical graph, but gives another view. If some nodes or |
---|
47 | edges have to be hidden or the reverse oriented graph have to be used, then |
---|
48 | this is the case. It also may happen that in a flow implementation |
---|
49 | the residual graph can be accessed by another algorithm, or a node-set |
---|
50 | is to be shrunk for another algorithm. |
---|
51 | LEMON also provides a variety of graphs for these requirements called |
---|
52 | \ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only |
---|
53 | in conjunction with other graph representation. |
---|
54 | |
---|
55 | You are free to use the graph structure that fit your requirements |
---|
56 | the best, most graph algorithms and auxiliary data structures can be used |
---|
57 | with any graph structures. |

397 | |

398 | - These classes declare every functions, <tt>typedef</tt>s etc. an |
---|
399 | implementation of the concepts should provide, however completely |
---|
400 | without implementations and real data structures behind the |
---|
401 | interface. On the other hand they should provide nothing else. All |
---|
402 | the algorithms working on a data structure meeting a certain concept |
---|
403 | should compile with these classes. (Though it will not run properly, |
---|
404 | of course.) In this way it is easily to check if an algorithm |
---|
405 | doesn't use any extra feature of a certain implementation. |
---|
406 | |
---|
407 | - The concept descriptor classes also provide a <em>checker class</em> |
---|
408 | that makes it possible check whether a certain implementation of a |
---|
409 | concept indeed provides all the required features. |
---|
410 | |
