摘要:

马尔可夫决策过程中的最大可达概率可以使用值迭代(VI)来计算。最近,基于仿真的启发式扩展VI,如有界实时动态规划(BRTDP),它往往设法避免整个状态空间的显式分析,同时保持对计算结果的保证。在本文中,我们介绍了一类新的算法,基于蒙特卡罗树搜索(MCTS),在各种机器学习设置庆祝的技术。我们提供了一系列的算法,从MCTS到BRTDP。我们评估这些技术,并表明,对于较大的例子,VI是没有更多的适用,我们的技术是更广泛的适用于比BRTDP只有一个小的额外开销。

英文摘要:

The maximum reachability probabilities in a Markov decision process can be computed using value iteration (VI). Recently, simulation-based heuristic extensions of VI have been introduced, such as bounded real-time dynamic programming (BRTDP), which often manage to avoid explicit analysis of the whole state space while preserving guarantees on the computed result. In this paper, we introduce a new class of such heuristics, based on Monte Carlo tree search (MCTS), a technique celebrated in various machine-learning settings. We provide a spectrum of algorithms ranging from MCTS to BRTDP. We evaluate these techniques and show that for larger examples, where VI is no more applicable, our techniques are more broadly applicable than BRTDP with only a minor additional overhead.
