报告摘要：This work explores the large-scale multi-agent communication mechanism for multi-agent reinforcement learning (MARL). We summarize the general categories of topology for communication structures, which are often manually specified in MARL literature. A novel framework termed Learning Structured Communication (LSC) is proposed by utilizing flexible and efficient communication topology. Our framework allows for adaptive agent grouping to form different hierarchical formations over episodes, which is generated by an auxiliary task combined with a hierarchical routing protocol. Given the formed topology, a hierarchical graph neural network is learned to enable effective message information generation and propagation among inter- and intra-group communications. In contrast to existing communication mechanisms, our method has an explicit while the learnable design for hierarchical communication. Experiments on challenging tasks, e.g., multi-agent path-finding of AGVs, show the proposed LSC performs high communication efficiency and global cooperation capability.
