ISOMORPHISM EXAMPLES, AND HW#2 Example 1.

WebThe Graph Isomorphism problem and the Coset Intersection problem can be solved in quasipolynomial time. The SI and CI problems were introduced by Luks [Lu82] (cf. [Lu93]) who also pointed out that these problems are polynomial-time equivalent (under Karp reductions) and GI easily reduces to either. WebISOMORPHISM EXAMPLES, AND HW#2 A good way to show that two graphs are isomorphic is to label the vertices of both graphs, using the same set labels for both graphs. This will determine an isomorphism if for all pairs of labels, either there is an edge between the vertices labels “a” and “b” in both graphs or there is not an edge between ... the politically correct term for gypsies

Webization problem for graphs is to produce a canonical form canon(G) for a given graph G such that canon(G) is isomorphic to Gand canon(G1) = canon(G2) for any pair of iso-morphic graphs G1 and G2. Canonization is clearly at least as hard as Graph Isomorphism.
