Fast Value Iteration for Goal-Directed Markov Decision Processes
Nevin Zhang, Weihong Zhang
Planning problems where effects of actions are non-deterministic can be modeled as Markov decision processes. Planning problems are usually goal-directed. This paper proposes several techniques for exploiting the goal-directedness to accelerate value iteration, a standard algorithm for solving Markov decision processes. Empirical studies have shown that the techniques can bring about significant speedups.
Keywords: Decision-theoretic planning, markov decision processes, value iteration, efficiency.
