Multi-Agent Robot Simulation for Evolutionary Learning of Cooperative Behavior

Yoichiro Maeda, Osaka Electro-Communication University

In this research, the evolutionary algorithm is applied to behavior learning of an individual agent in the multi-agent robot system. Each agent robot is given two behavior duties both collision avoidance from the other agent and target (food point) reaching for recovering self-energy. In this paper, we carried out the evolutionary simulation of the cooperative behavior creating an environmentla map for the above-mentioned multi-agent robots. Each agent robot has two confliced tasks, that is, local individual behaviors for self preservation or self-protection and global group behaviors for the cooperative task, and has the additional algorithm of the group evolution which the parameters of the best agent are copies to a dead agent, that is, an agent lost its energy. we also report simulation results performed with the evolutionary behavior learning simulator which we developed for multi-agent robots with the map creation task.
