New MARL method HIBCG optimizes agent communication graphs

Researchers have introduced Heterogeneous Information-Bottleneck Coordination Graphs (HIBCG), a novel approach to multi-agent reinforcement learning. HIBCG addresses limitations in existing methods by providing a theoretically grounded mechanism for determining the existence and information capacity of communication edges between agents. The proposed method constructs a group-aligned sparse graph and controls message bandwidth, ensuring that only task-relevant information is communicated, which is proven to tighten the learning bound and enable differential edge control.
