离散势平均场对策:对偶性与数值解析

Discrete potential mean field games: duality and numerical resolution

J. Frédéric Bonnans, Pierre Lavigne, Laurent Pfeiffer

摘要:

提出并研究了一类具有势结构的离散时间有限状态空间平均场对策问题。我们的模型通过一个拥塞项和一个价格变量结合了相互作用。它还允许对代理的分布进行硬约束。我们分析了MFG问题和两个最优控制最优控制问题之间的对偶关系。我们提出了两个家庭的数值方法,并详细介绍了他们的实施:(一)原始-对偶邻近方法(及其扩展与非线性邻近算子),(二)的交替方向法的乘法器(ADMM)和一个变种称为ADM-G。我们给出了一些收敛结果。数值结果提供了两个例子与硬约束。

英文摘要:

We propose and investigate a general class of discrete time and finite state space mean field game (MFG) problems with potential structure. Our model incorporates interactions through a congestion term and a price variable. It also allows hard constraints on the distribution of the agents. We analyze the connection between the MFG problem and two optimal control problems in duality. We present two families of numerical methods and detail their implementation: (i) primal-dual proximal methods (and their extension with nonlinear proximity operators), (ii) the alternating direction method of multipliers (ADMM) and a variant called ADM-G. We give some convergence results. Numerical results are provided for two examples with hard constraints.
