WebNP-complete problems in graphs, such as enumeration and the selection of subgraphs with given characteristics, become especially relevant for large graphs and networks. Herein, particular statements with constraints are proposed to solve such problems, and subclasses of graphs are distinguished.

WebThe graph isomorphism problem is the computational problem of determining whether two finite graphs are isomorphic. The graph isomorphism problem is neither NP complete, co-NP or P so its in a class of its own called the GI class. The class GI is a set of problems with a polynomial time Turing reduction to the graph isomorphism problem.
