CP Models for Maximum Common Subgraph Problems

摘要

The distance between two graphs is usually defined by means of the size of a largest common subgraph. This common subgraph may be an induced subgraph, obtained by removing nodes, or a partial subgraph, obtained by removing arcs and nodes. In this paper, we introduce two soft CSPs which model these two maximum common subgraph problems in a unified framework. We also introduce and compare different CP models, corresponding to different levels of constraint propagation.
