Graph matching problem

WebMatching. Let ‘G’ = (V, E) be a graph. A subgraph is called a matching M (G), if each vertex of G is incident with at most one edge in M, i.e., deg (V) ≤ 1 ∀ V ∈ G. which means … 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.

To think of matching this way, we associate a variable x ewith every edge e2E. We would like to think of these variables taking values 0 or 1 with x e= 1 indicating that edge ein the matching, and 0 when its not in the matching. To write the maximum 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.
