摘要:

本文考虑了一个受群体运动模型启发的平均场博弈模型,其中智能体旨在到达给定目标集,并希望最小化由个体运行成本、取决于到达目标集时间的个体成本以及以通过位置和速度与其他智能体成对相互作用形式存在的相互作用运行成本组成的成本。我们将此博弈归入具有成对相互作用的抽象波兰空间上更一般的博弈类中,证明后者博弈具有变分结构(即其均衡可表征为某些势泛函的临界点)并存在均衡。我们还讨论了两种先验不同的均衡概念,给出了两者重合的充分条件。抽象波兰空间中博弈的结果应用于我们的平均场博弈模型,文末给出了数值示例。

英文摘要:

This article considers a mean field game model inspired by crowd motion models in which agents aim at reaching a given target set and wish to minimize a cost consisting of an individual running cost, an individual cost depending on the arrival time at the target set, and an interaction running cost, which takes the form of pairwise interactions with other agents through both positions and velocities. We subsume this game under a more general class of games on abstract Polish spaces with pairwise interactions, and prove that the latter games have a variational structure (in the sense that their equilibria can be characterized as critical points of some potential functional) and admit equilibria. We also discuss two a priori distinct notions of equilibria, providing a sufficient condition under which both notions coincide. The results for the games in abstract Polish spaces are applied to our mean field game model, and a numerical illustration concludes the paper.
