摘要

通信效率和隐私保护是多智能体系统寻求分布式纳什均衡时面临的两个关键挑战。在本文中,我们提出了一种新的CGT-DPA算法,该算法集成了梯度跟踪以增强信息聚合并保证收敛性,同时结合了通信压缩以显著降低通信开销。此外,该算法执行差分隐私,在分布式设置中提供强大的隐私保证。严格证明了CGT-DPA在强单调映射下收敛到NE的一个邻域。理论分析和数值仿真验证了CGT-DPA在平衡通信效率、隐私保护和收敛性方面的有效性。

Differentially private distributed nash equilibrium seeking based on gradient tracking and communication compression
Communication efficiency and privacy preservation are two critical challenges in distributed Nash equilibrium (NE) seeking for multi-agent systems. In this paper, we propose a novel algorithm, CGT-DPA, which integrates gradient tracking to enhance information aggregation and ensure convergence, while incorporating communication compression to significantly reduce communication overhead. Additionally, the algorithm enforces differential privacy, providing strong privacy guarantees in distributed settings. We rigorously prove that CGT-DPA achieves linear convergence to a neighborhood of the NE under strongly monotone mappings. Both theoretical analysis and numerical simulations validate the effectiveness of CGT-DPA in balancing communication efficiency, privacy preservation and convergence.

期刊介绍: Founded in 1981 by two of the pre-eminent control theorists, Roger Brockett and Jan Willems, Systems & Control Letters is one of the leading journals in the field of control theory. The aim of the journal is to allow dissemination of relatively concise but highly original contributions whose high initial quality enables a relatively rapid review process. All aspects of the fields of systems and control are covered, especially mathematically-oriented and theoretical papers that have a clear relevance to engineering, physical and biological sciences, and even economics. Application-oriented papers with sophisticated and rigorous mathematical elements are also welcome.
