K-graph C*-algebra
Given two graphs and , the maximum common edge subgraph problem is the problem of finding a graph with a maximal number of edges which is isomorphic to a subgraph of and a subgraph of .
The maximum common edge subgraph problem on general graphs is NP-complete as it is a generalization of subgraph isomorphism. Unless and are required to have the same number of vertices, the problem is APX-hard.[1]
