摘要：
Many algorithms to solve subgraph isomorphism problems have been proposed and proven to be NP-hard, but they did not demonstrate promising results especially on the large and dense graphs. In this paper, a new algorithm for determining an induced subgraph isomorphism between pattern and target graphs is proposed. It is based on decomposition of a graph into components and refinements. The incident matrices are used to help in rearranging the vertices in a descending order and reducing the search efforts. The algorithm is analyzed from complexity point of view to demonstrate its effectiveness after applying it on several types of graphs.
