| Abstract(in English) | We propose a method using the policy gradient for reinforcement learning in multi-agent systems. In our approach, motion planning problems in multi-agent systems are formulated as problems that each agent selects its actions to minimize each objective function independently. The objective function can be defined by a state-value function, the sum of weight parameters of state-action rules, and heuristic potentials. The functions include some parameters. The parameters are updated stochastically in order to maximize the expectation of the reward based on a history of states and actions in each episode. The results of experiments for the pursuit problem showed that our method can make short episode plans as Q-learning does, and can easily deal with limitations such as time-window restrictions imposed on the episode length and heuristic knowledge such as an attractive potential to the target. |
