Discrete-time Stochastic Multi-agent Graphical Games with Multiplicative Noise:Reinforcement Learning Solutions

第30届中国控制与决策会议

作者： bingchang wang Minyi Huang School of Control Science and Engineering Shandong University School of Mathematics and Statistics Carleton University

This paper investigates mean field games for dynamic production competition. We first introduce a market of many firms with the sticky price and adjustment costs, where the price is disturbed by a Wiener process. By solving forward-backward stochastic differential equations subject to consistent mean field approximations, a set of decentralized strategies is obtained and further shown to be an ε-Nash equilibrium.

第43届中国控制会议

作者： Hanfang Zhang bingchang wang Shandong University

This paper considers a discrete time stochastic multi-agent graphical games problem with multiplicative noise based on reinforcement learning. The Bellman optimality equations for multi-agent graphical games are obtained by using the optimality principle. Through the stability analysis, it is proved that the solutions of the equations converge to Nash equilibrium. Since the coupled Bellman equation is difficult to solve, the value iteration heuristic dynamic programming(HDP) algorithm is *** solve multi-agent graphical games online, the HDP algorithm based on the actor-critic framework is designed to find the approximate solutions, and the effectiveness of the algorithm is verified by a simulation example.
