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 ... WebMatching algorithms are algorithms used to solve graph matching problems in graph theory. A matching problem arises when a set of edges must be drawn that do not share any vertices.
