有限理性追逃对策

Bounded-Rational Pursuit-Evasion Games

Yue Guan, Dipankar Maity, Christopher M. Kroninger, Panagiotis Tsiotras

摘要:

我们提出了一个框架,将有限理性的思想纳入动态随机追求-逃避游戏。随机博弈的解一般由其反馈形式的(纳什)均衡来表征。然而,计算这些纳什均衡策略可能需要大量的计算资源。在本文中,代理建模为有限的计算资源有限的有界理性实体。我们说明了框架,将其应用到两辆车之间的追逐-逃避游戏在随机风场,追逐者和逃避者都有界理性。我们展示了如何这样的游戏可以通过适当铸造它作为一个迭代序列的有限状态马尔可夫决策过程(MDP)进行分析。利用认知层次理论的工具和算法(“水平- $k$思维”),我们计算随后的离散游戏的解决方案,同时考虑到每个代理的合理性水平。我们还提出了一个在线算法,每个代理推断其对手的合理性水平。

英文摘要:

We present a framework that incorporates the idea of bounded rationality into dynamic stochastic pursuit-evasion games. The solution of a stochastic game is characterized, in general, by its (Nash) equilibria in feedback form. However, computing these Nash equilibrium strategies may require extensive computational resources. In this paper, the agents are modeled as bounded rational entities having limited computational resources. We illustrate the framework by applying it to a pursuit-evasion game between two vehicles in a stochastic wind field, where both the pursuer and the evader are bounded rational. We show how such a game may be analyzed by properly casting it as an iterative sequence of finite-state Markov Decision Processes (MDPs). Leveraging tools and algorithms from cognitive hierarchy theory ("level-$k$ thinking") we compute the solution of the ensuing discrete game, while taking into consideration the rationality level of each agent. We also present an online algorithm for each agent to infer its opponent rationality level.
