Guided Symbolic Universal Planning
Date of Original Version
Abstract or Description
Symbolic universal planning based on the reduced Ordered Binary Decision Diagram (OBDD) has been shown to be an efficient approach for planning in non-deterministic domains. To date, however, no guided algorithms exist for synthesizing universal plans. In this paper, we introduce a general approach for guiding universal planning based on an existing method for heuristic symbolic search in deterministic domains. We present three new sound and complete algorithms for best-first strong, strong cyclic, and weak universal planning. Our experimental results show that guiding the search dramatically can reduce both the computation time and the size of the generated plans.
