In other words, a matching is a graph where each node has either zero or one edge incident to it. Graph matching is not to be confused with graph isomorphism. Graph isomorphism checks if two graphs are the same whereas a ...

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 matching in a bipartite graph can be treated as a network flow problem.
