## Summary

This paper systematically studies the mechanisms, scaling behavior, and generalization of physical recursive self-improvement (RSI) in embodied agents, proposing PhysRSI-eval, which quantifies physical RSI across five dimensions: first-attempt performance, efficiency, success rate, budget, and improvement from failure, and evaluates multiple VLMs on 18 manipulation tasks under a fixed interaction budget.
