WebOct 18, 2014 · Graph isomorphism An equivalence relation on the set of graphs. An isomorphic mapping of a non-oriented graph to another one is a one-to-one mapping of the vertices and the edges of one graph onto the vertices and the edges, respectively, of the other, the incidence relation being preserved. The graph isomorphism problem is the computational problem of determining whether two finite graphs are isomorphic. The problem is not known to be solvable in polynomial time nor to be NP-complete, and therefore may be in the computational complexity class NP-intermediate. It is known that the graph isomorphism problem is in the low hierarchy of class NP, which implies that it is not NP-complete …
