Abstract

The subgraph isomorphism problem, the goal of which is to find the occurrences of a given pattern graph in a given host graph, is, owing to the pervasiveness of large networks, becoming increasingly important. However, the problem is NP-complete, and the search efficiency may also be negatively affected by symmetries in the pattern graph. In this paper, we present an algorithm for solving the subgraph isomorphism problem using a search plan, a sequence of instructions for a systematic traversal of the pattern graph. The presented algorithm pays attention to the symmetries in the pattern graph and thus performs more efficiently than its straightforward counterpart which merely follows the search plan instructions in all possible ways. By testing our algorithm on artificial and real-world graphs, we empirically confirm its advantage over the naive approach and answer several research questions. [ABSTRACT FROM AUTHOR]
