AgentPSO: Evolving Agent Reasoning Skill via Multi-agent Particle Swarm Optimization

arXiv:2605.08704v2 Announce Type: replace Abstract: Multi-agent reasoning has shown promise for improving the problem-solving ability of large language models by allowing multiple agents to explore diverse reasoning paths. However, most existing multi-agent methods rely on inference-time debate or aggregation, which can be vulnerable to incorrect peer influence and biased consensus. Moreover, the agents themselves remain static, as their underlying reasoning skills do not evolve across tasks. In this paper, we introduce \textbf{AgentPSO}, a particle-swarm-inspired framework for evolving multi-

Why this matters
Why now

The rapid advancement in large language models has exposed limitations in static multi-agent reasoning, making the evolution of agent skills crucial for sustained progress in AI problem-solving.

Why it’s important

Improving the evolutionary capabilities of AI agents directly addresses current vulnerabilities in multi-agent systems and accelerates the development of more robust, autonomous AI.

What changes

AI agents will transition from static models to dynamic, evolving entities, enhancing their reasoning skills across diverse tasks and reducing reliance on fixed inference-time processes.
