Researchers have introduced Gradient Guided Multi Agent Flow (G2MAF), a novel framework designed to refine multi-agent reinforcement learning policies at test-time. This method addresses the issue of frozen policies making suboptimal joint action proposals by applying a globally normalized, projected critic gradient. G2MAF guides agents to make corrections while ensuring actions remain feasible and close to the original proposal. In evaluations across 24 Multi-Agent Particle Environment (MPE) and SMAC settings, G2MAF improved 20 frozen policies, achieving average relative gains of 9.2% on MPE and 8.9% on SMAC with only a 6% increase in inference latency.
