WebIn graph theory, a matching in a graph is a set of edges that do not have a set of common vertices. 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 matching is a particular … WebThe goal is to find as many valid assignments as possible, such that each student can only take one job and each job can only be performed by a single student. Let \ ( G= (V,E)\) be a given undirected graph. A subset \ (M \subseteq E\) is called a matching, if no two edges in M share a node. A matching M is called maximal, if the cardinality of ...
