Approximate Graph Matching: approaches and a tool Dennis Shasha Abstract: Approximate graph isomorphism and subgraph isomorphism are known to be NP-complete. After studying many different heuristic approaches to this problem, we have worked out some new ones that work extremely well on random data and on real data from the National Cancer Institute. The software is available and requires about 5 minutes to download and start to use. This talk discusses the problem, some approaches including ours, and our experimental results.
