Consider the Subgraph Isomorphism problem: Input: two undirected graphs G and H.Output: determine whether G is a subgraph of H (that is, whether by deleting certain vertices and edges of H we obtain a graph that is, up to renaming of vertices, identical to G). The Subgraph Isomorphism problem can be shown to be NP-hard because it is a generalization of
