重复博弈的近似子博弈完美均衡计算技术

An Approximate Subgame-Perfect Equilibrium Computation Technique for Repeated Games

Andriy Burkov, Brahim Chaib-draa

摘要:

本文提出了一种近似的技术,以任何精度,子博弈完美均衡(SPE)的折扣重复游戏。该过程从SPE集合的单个超立方体近似开始。然后将初始超立方体逐渐划分为一组较小的相邻超立方体,而那些不包含任何属于SPE集合的点的超立方体同时被撤回。通过适当的数学程序验证了一个给定的超立方体是否可以包含一个平衡点。三种不同的配方的算法都近似计算的SPE支付和提取球员的策略,然后提出:前两个,不假设存在的外部协调球员之间,第三个,假设一定程度的协调,在游戏过程中凸化的连续支付后,任何重复的游戏历史。一个特别注意的问题,提取球员的策略和他们的有限自动机的形式,人工智能体系统的一个重要功能的可表示性。

英文摘要:

This paper presents a technique for approximating, up to any precision, the set of subgame-perfect equilibria (SPE) in discounted repeated games. The process starts with a single hypercube approximation of the set of SPE. Then the initial hypercube is gradually partitioned on to a set of smaller adjacent hypercubes, while those hypercubes that cannot contain any point belonging to the set of SPE are simultaneously withdrawn. Whether a given hypercube can contain an equilibrium point is verified by an appropriate mathematical program. Three different formulations of the algorithm for both approximately computing the set of SPE payoffs and extracting players' strategies are then proposed: the first two that do not assume the presence of an external coordination between players, and the third one that assumes a certain level of coordination during game play for convexifying the set of continuation payoffs after any repeated game history. A special attention is paid to the question of extracting players' strategies and their representability in form of finite automata, an important feature for artificial agent systems.
