Graph theory matching
WebGiven an undirected graph, a matching is a set of edges, no two sharing a vertex. A vertex is matched if it has an end in the matching, free if not. A matching is perfect if all vertices are matched. Goal: In a given graph, find a matching containing as many edges as possible: a maximum-size matching Special case : Find a perfect matching (or ...

WebJun 24, 2015 · A perfect matching is a matching which matches all vertices of the graph. A maximum matching is a matching that contains the largest possible number of edges. If we added an edge to a perfect matching it would no longer be a matching. To be a perfect matching of a graph G = ( V, E), it must have V / 2 edges, and thus V must be even.
