Matching (graph theory)
In the mathematical discipline of graph theory, a matching or independent edge set in an undirected graph is a set of edges without common vertices. In other words, a subset of the edges is a matching if each vertex appears in at most one edge of that matching. Finding a largest matching in a bipartite graph can be treated as a network flow problem. Finding a largest matching in a general graph is much more difficult; it can be done using Edmonds' blossom algorithm.
