r236 r325 41 41 some graph features like arc/edge or node deletion. 42 42 43 Alteration of standard containers need a very limited number of44 operations, these together satisfy the everyday requirements.45 In the case of graph structures, different operations are needed which do46 not alter the physical graph, but gives another view. If some nodes or47 arcs have to be hidden or the reverse oriented graph have to be used, then48 this is the case. It also may happen that in a flow implementation49 the residual graph can be accessed by another algorithm, or a nodeset50 is to be shrunk for another algorithm.51 LEMON also provides a variety of graphs for these requirements called52 \ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only53 in conjunction with other graph representations.54 55 43 You are free to use the graph structure that fit your requirements 56 44 the best, most graph algorithms and auxiliary data structures can be used 57 45 with any graph structures. 58 */59 60 /**61 @defgroup semi_adaptors SemiAdaptor Classes for Graphs62 @ingroup graphs63 \brief Graph types between real graphs and graph adaptors.64 65 This group describes some graph types between real graphs and graph adaptors.66 These classes wrap graphs to give new functionality as the adaptors do it.67 On the other hand they are not lightweight structures as the adaptors.68 46 */ 69 47 … … 153 131 154 132 /** 155 @defgroup matrices Matrices156 @ingroup datas157 \brief Two dimensional data storages implemented in LEMON.158 159 This group describes two dimensional data storages implemented in LEMON.160 */161 162 /**163 133 @defgroup paths Path Structures 164 134 @ingroup datas … … 214 184 215 185 /** 216 @defgroup max_flow Maximum Flow algorithms217 @ingroup algs218 \brief Algorithms for finding maximum flows.219 220 This group describes the algorithms for finding maximum flows and221 feasible circulations.222 223 The maximum flow problem is to find a flow between a single source and224 a single target that is maximum.
