Py Bipartite Matching contains bipartite graphs matching algorithms.

Py Bipartite Matching

Algorithms for Enumerating All Perfect, Maximum and Maximal Matchings in Bipartite Graphs.

Algorithm described in “Algorithms for Enumerating All Perfect, Maximum and Maximal Matchings in Bipartite Graphs” By Takeaki Uno in “Algorithms and Computation: 8th International Symposium, ISAAC ‘97 Singapore, December 17-19, 1997 Proceedings” See http://dx.doi.org/10.1007/3-540-63890-3_11

• Documentation: https://py-bipartite-matching.readthedocs.io.

Features

• Functions available:

  • enum_perfect_matchings

  • enum_maximum_matchings

usage

To use Py Bipartite Matching in a project the networkx package is needed as well

>>> import py_bipartite_matching as pbm
>>> import networkx as nx

Use enum_perfect_matchings to enumerate all perfect matchings

>>> n = 2
>>> graph = nx.complete_bipartite_graph(n, n, nx.Graph)
>>> for matching in pbm.enum_perfect_matchings(graph):
>>>     print(matching)

    {0: 2, 1: 3}
    {0: 3, 1: 2}

Use enum_maximum_matchings to enumerate all maximum matchings

>>> n = 2
>>> m = 3
>>> graph = nx.complete_bipartite_graph(n, m, nx.Graph)
>>> for matching in enum_maximum_matchings(graph):
>>>     print(matching)

    {0: 3, 1: 4}
    {0: 4, 1: 3}
    {0: 3, 2: 4}
    {1: 3, 2: 4}
    {0: 4, 2: 3}
    {2: 3, 1: 4}
