Multi-agent reinforcement learning (MARL) has long been a significant and everlasting research topic in both machine learning and control. With the recent development of (single-agent) deep RL, there is a resurgence of interests in developing new MARL algorithms, especially those that are backed by theoretical analysis. In this paper, we review some recent advances a sub-area of this topic: decentralized MARL with networked agents. Specifically, multiple agents perform sequential decision-making in a common environment, without the coordination of any central controller. Instead, the agents are allowed to exchange information with their neighbors over a communication network. Such a setting finds broad applications in the control and operation of robots, unmanned vehicles, mobile sensor networks, and smart grid. This review is built upon several our research endeavors in this direction, together with some progresses made by other researchers along the line. We hope this review to inspire the devotion of more research efforts to this exciting yet challenging area.

本文回顾了多智能体强化学习的一个分支领域——网络化智能体下的去中心化多智能体强化学习。该领域的研究主要集中在多个代理在公共环境中执行顺序决策，而无需任何中央控制器的协调。代理可以通过通信网络与其邻居交换信息。此设置在机器人，无人驾驶车辆，移动传感器网络和智能电网的控制和操作中具有广泛应用。
