Abstract: In this paper, a new isomorphism testing algorithm for directed graphs——the in-degree and out-degree sequence method——is presented. The algorithm can be used in many pattern recognition problems that can be described by directed graphs.

Key words: graph isomorphism, graph theory algorithm, out-degree sequence, in-degree sequence
