| Abstract(in English) | We analyze Multi-State Commitment(MSC) Search algorithms which are heuristic search algorithms for semi-optimal solutions. We compare MSC-RTA^* with the original RTA^* on 15-puzzle, tower of hanoi, and maze problems, and show that if a problem has serializable subgoals, or a stage-space graph which have states with identical heuristic values, MSC-RTA^* can show superiority over RTA^*. We then show that NSC-WA^* can find solution with fewer state expansions than original WA^* on the problems in which cutting branches is effective. Finally, we make three artificial models with these properties espectively, and verify the performance by experiments on the models. |
