RSEA: Recursive Self-Evolving Agent Without Weight Updates – Comprehensive Study

Study Summary

FAQ

What is the RSEA agent?

RSEA is an AI agent that recursively rewrites its strategies, skills, and procedures based on its own trajectories, with a strict held-out selection gate to ensure no regression from the base agent performance.

How does RSEA compare to ReAct?

On ALFWorld, RSEA achieves 69.3% compared to 64.6% for ReAct, with significant statistical improvement (p=0.015).

Can RSEA be used in MENA applications?

Yes, teams in the region can adopt RSEA to improve agent performance in complex tasks like tool use and web search without needing weight updates.
