Bridging MARL to SARL: An Order-Independent Multi-Agent Transformer via Latent Consensus

Jing Gao, Sen Li, Zijian Zhao

Claims

C1strongest claim

CMAT bridges cooperative MARL to a hierarchical SARL formulation by autoregressively generating a high-level consensus vector that conditions simultaneous, order-independent action generation, allowing optimization with single-agent PPO while achieving superior performance on StarCraft II, Multi-Agent MuJoCo, and Google Research Football benchmarks.

C2weakest assumption

The latent consensus vector produced by the transformer decoder actually captures sufficient coordination information to replace explicit agent-to-agent communication or centralized critics without loss of expressivity; this is assumed rather than proven and is only supported by empirical wins on the chosen benchmarks.

C3one line summary

CMAT uses a transformer decoder to produce a high-level consensus vector in latent space, enabling simultaneous order-independent actions by all agents and optimization via single-agent PPO, with superior results on StarCraft II, Multi-Agent MuJoCo, and Google Research Football.
