When Does Multi-Agent Collaboration Help? An Entropy Perspective

In three linesEmpirical study of 245 entropy features (token, agent, round) across 6 reasoning benchmarks and 2 agentic tasks. Counterintuitive finding: single agent outperforms MAS in 43.3% of cases. Three key observations: certainty preference, base entropy drives performance, task-dependent entropy dynamics. Entropy Judger algorithm proposed to select MAS solutions.
