A backtrack algorithm is described to test two digraphs for isomorphism. Use is made of the degree sequence of vertices and a recursive procedure, using the distance matrices, to obtain the initial partitioning of vertices. The backtrack procedure maps vertices by composing rows and columns of the distance matrix.
Abstract. A reasonably efficient procedure for testing pairs of directed graphs for isomorphism is important in information retrieval and other application ...
Every node correspondence defining a graph isomorphism has to be examined to see whether it carries across to the digraphs. In the worst case this is again an n ...
