A Counter-Example Based Approach to Probabilistic Conformant Planning

Abstract

This paper introduces a counter-example based approach, P-CPCES, for solving probabilistic conformant planning (PCP) problems. Our algorithm incrementally generates candidate plans and identifies counter-examples until it finds a plan for which the probability of success is above the specified threshold. We prove that the algorithm is sound and complete. We further propose a variation of our algorithm, P-CPCES-HIT, that uses hitting sets to accelerate the generation of candidate plans. Experimental results show that our planner is particularly suited for problems with a high probability threshold. Show more
