Measurement of underlying cooperation in multiagent reinforcement learning

Abstract

Although a large number of algorithms have been proposed for generating cooperative behaviors, the question of how to evaluate mutual benefit among them is still open. This study provides a measure for cooperation degree among the reinforcement learning agents. By means of our proposed measure, that is based on information theory, the degree of interaction among agents can be evaluated from the viewpoint of information sharing. Here, we show the availability of this measure through some experiments on "pursuit game", and evaluate the degree of cooperation among hunters and prey. © 2008 Springer Berlin Heidelberg.
