On reward distribution in reinforcement learning of multi-agent surveillance systems with temporal logic specifications

Abstract

In multi-agent systems, it is important to design a reward based on the contribution of each agent for efficient learning. In this paper, we propose a reward distribution method for a surveillance system based on our previously proposed multi-agent reinforcement learning method with an aggregator, in which a control specification is described by a linear temporal logic formula. In this method, the aggregator computes and distributes rewards according to the actions that agents take on the surveillance system. Finally, the effectiveness of the proposed method is presented through a numerical simulation of a surveillance problem addressing a specific type of linear temporal logic specification.
