Abstract

In real-world games involving autonomous agents making decisions under uncertainty [1], the agents are often subject to sensing and communication limitations. In these cases, it is desirable to win the game, while also minimizing an agent’s sensing budget. In particular, in two-player uncertain adversarial environments, where one player enters the opponent’s territory, we seek a wining strategy with minimum sensing. In this paper, we consider finite two-player stochastic games, wherein in addition to the conventional cost over states and actions of each player, we include the sensing budget in terms of transfer entropy. We find a set of pure and mixed strategies for such a game via dynamic programming. The application of dynamic programming leads to a set of coupled nonlinear equations that we solve using the modified Arimoto-Blahut algorithm. The efficacy of the proposed method is illustrated by a stochastic unmanned aerial vehicle (UAV) pursuit-evasion game example using the tool AMASE.
具有感知代价的随机对策
在现实世界的游戏中,涉及在不确定性b[1]下做出决策的自主代理,代理通常受到传感和通信限制。在这些情况下,赢得游戏是理想的,同时也最小化代理的感知预算。特别是在两名玩家不确定的对抗环境中,当一名玩家进入对手的领土时,我们会寻求一种具有最小感知的获胜策略。在本文中,我们考虑了有限的二人随机博弈,其中除了每个参与者的状态和行动的传统成本外,我们还包括了传输熵方面的感知预算。我们通过动态规划找到了一组纯策略和混合策略。动态规划的应用产生了一组耦合非线性方程,我们使用改进的Arimoto-Blahut算法求解。最后,利用AMASE工具对随机无人机追逃博弈进行了仿真,验证了该方法的有效性。
