加法耦合和约束对策的结构解

Structural Solutions For Additively Coupled Sum Constrained Games

Yi Su, Mihaela van der Schaar

摘要:

我们提出并分析了一个由资源受限玩家参与的游戏家族,其主要特征是:1)每个用户都有一个多维的行动空间,服从单一的资源限制:2)每个用户在特定维度上的效用依赖于同一维度上的用户行动与其他用户行动之间的加性耦合; 3)每个用户的总效用是在每个维度上获得的效用之和。通信系统中这种多用户环境的常见例子包括频率选择性高斯干扰信道上的功率控制和Jackson网络中的流量控制。在用户无法实时交换消息的情况下,我们研究了用户如何根据本地观察调整他们的行为。我们得到了一个唯一的纳什均衡存在的充分条件下,最佳对策算法全局和线性收敛到纳什均衡。在用户可以实时交换消息的设置中,我们专注于优化整体实用程序的用户选择。给出了梯度播放和Jacobi更新两种分布式动作更新机制的收敛条件。

英文摘要:

We propose and analyze a broad family of games played by resource-constrained players, which are characterized by the following central features: 1) each user has a multi-dimensional action space, subject to a single sum resource constraint; 2) each user's utility in a particular dimension depends on an additive coupling between the user's action in the same dimension and the actions of the other users; and 3) each user's total utility is the sum of the utilities obtained in each dimension. Familiar examples of such multi-user environments in communication systems include power control over frequency-selective Gaussian interference channels and flow control in Jackson networks. In settings where users cannot exchange messages in real-time, we study how users can adjust their actions based on their local observations. We derive sufficient conditions under which a unique Nash equilibrium exists and the best-response algorithm converges globally and linearly to the Nash equilibrium. In settings where users can exchange messages in real-time, we focus on user choices that optimize the overall utility. We provide the convergence conditions of two distributed action update mechanisms, gradient play and Jacobi update.
