    296  - \ref Dijkstra algorithm for finding shortest paths from a source node
    297    when all arc lengths are non-negative.
    298  - \ref BellmanFord "Bellman-Ford" algorithm for finding shortest paths
    299    from a source node when arc lenghts can be either positive or negative,
    300    but the digraph should not contain directed cycles with negative total
    301    length.
    302  - \ref FloydWarshall "Floyd-Warshall" and \ref Johnson "Johnson" algorithms
    303    for solving the \e all-pairs \e shortest \e paths \e problem when arc
    304    lenghts can be either positive or negative, but the digraph should
    305    not contain directed cycles with negative total length.
     288 - \ref Dijkstra Dijkstra's algorithm for finding shortest paths from a
     289   source node when all arc lengths are non-negative.
    306290 - \ref Suurballe A successive shortest path algorithm for finding
    307291   arc-disjoint paths between two nodes having minimum total length.

    330 LEMON contains several algorithms for solving maximum flow problems:
    331 - \ref EdmondsKarp Edmonds-Karp algorithm.
    332 - \ref Preflow Goldberg-Tarjan's preflow push-relabel algorithm.
    333 - \ref DinitzSleatorTarjan Dinitz's blocking flow algorithm with dynamic trees.
    334 - \ref GoldbergTarjan Preflow push-relabel algorithm with dynamic trees.
    335 
    336 In most cases the \ref Preflow "Preflow" algorithm provides the
    337 fastest method for computing a maximum flow. All implementations
    338 provides functions to also query the minimum cut, which is the dual
    339 problem of the maximum flow.
     314\ref Preflow implements the preflow push-relabel algorithm of Goldberg and
     315Tarjan for solving this problem. It also provides functions to query the
     316minimum cut, which is the dual problem of maximum flow.
     317
     318\ref Circulation is a preflow push-relabel algorithm implemented directly
     319for finding feasible circulations, which is a somewhat different problem,
     320but it is strongly related to maximum flow.
     321For more information, see \ref Circulation.

    423405
    424 All algorithms provide dual solution (node potentials) as well,
    425 if an optimal flow is found.
    426 
    427 LEMON contains several algorithms for solving minimum cost flow problems.
    428  - \ref NetworkSimplex Primal Network Simplex algorithm with various
    429    pivot strategies.
    430  - \ref CostScaling Push-Relabel and Augment-Relabel algorithms based on
    431    cost scaling.
    432  - \ref CapacityScaling Successive Shortest %Path algorithm with optional
    433    capacity scaling.
    434  - \ref CancelAndTighten The Cancel and Tighten algorithm.
    435  - \ref CycleCanceling Cycle-Canceling algorithms.
    436 
    437 Most of these implementations support the general inequality form of the
    438 minimum cost flow problem, but CancelAndTighten and CycleCanceling
    439 only support the equality form due to the primal method they use.
    440 
    441 In general NetworkSimplex is the most efficient implementation,
    442 but in special cases other algorithms could be faster.
    443 For example, if the total supply and/or capacities are rather small,
    444 CapacityScaling is usually the fastest algorithm (without effective scaling).
     406\ref NetworkSimplex is an efficient implementation of the primal Network
     407Simplex algorithm for finding minimum cost flows. It also provides dual
     408solution (node potentials), if an optimal flow is found.

    469   calculating minimum cut in undirected graphs.

    506 This group contains the algorithms for calculating

    511460There are several different algorithms for calculate matchings in
