The Bipartite Matching Problem

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 … See more Given a graph G = (V, E), a matching M in G is a set of pairwise non-adjacent edges, none of which are loops; that is, no two edges share common vertices. A vertex is matched (or saturated) if it is an endpoint of one … See more Maximum-cardinality matching A fundamental problem in combinatorial optimization is finding a maximum matching. This problem has various algorithms for … See more Kőnig's theorem states that, in bipartite graphs, the maximum matching is equal in size to the minimum vertex cover.

WebGraph matching refers to the problem of finding a mapping between the nodes of one graph ( A ) and the nodes of some other graph, B. For now, consider the case where the two networks have exactly the same number of nodes. Then, this problem amounts to finding a permutation of the nodes of one network with regard to the nodes of the other.
