Input: We document a connection between constraint reasoning and probabilistic reasoning. We present an algorithm, called probabilistic arc consistency, which is both a generalization of a well known algorithm for arc consistency used in constraint reasoning, and a specialization of the belief updating algorithm for singly-connected networks. Our algorithm is exact for singly­ connected constraint problems, but can work well as an approximation for arbitrary problems. We briefly discuss some empirical results, and re­ lated methods.
