A Heuristic Approach for Solving Decentralized-POMDP : Assessment on the Pursuit Problem

Résumé

Defining the behaviour of a set of situated agents, such that a collaborative problem can be solved is a key issue in multi-agent systems. In this paper, we formulate this problem from the decision theoretic perspective using the framework of Decentralized Partially Observable Markov Decision Processes (DEC-POMDP). Formulating the coordination problem in this way provides a formal foundation for study of cooperation activities. But, as it has been recently shown solving DEC-POMDP is NEXP-complete and thus it is not a realistic approach for the design of agent cooperation policies. However, we demonstrate in this paper that it is not completely desperate. Indeed, we propose an heuristic approach for solving DEC-POMDP when agents are memoryless and when the global reward function can be broken up into a sum of local reward functions. We demonstrate experimentally on an example (the so-called pursuit problem) that this heuristic is efficient within a few iteration steps.
