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 … WebFeb 13, 1987 · A b-matching of a given graph G is an assignment of integer weights to the edges of G so that the sum of the weights on the edges incident with a vertex v is at …

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.
