(English Abstract)
In this paper, we present a new heuristic search algorithm, HSCP, that can solve conditional/contingent planning problems with nondeterministic actions as well as partial observations. The algorithm repeats its AND-OR search trials until a complete solution graph can be found. However, unlike existing heuristic AND-OR search algorithms such as AO* and LAO*, the AND-OR search trial conducted by HSCP concentrates on only a single candidate of solution subgraphs to expand it into a complete solution graph. Moreover, unlike real-time dynamic programming algorithms such as RTDP and LRTDP, the AND-OR search trial of HSCP finds a solution immediately when it possible without delaying it until the estimated value of every state converges. Therefore, the HSCP search algorithm has the advantage that it can find a sub-optimal conditional plan very efficiently.
