From Procedural Skills to Strategy Genes: Towards Experience-Driven Test-Time Evolution

Excerpt

arXiv:2604.15097v4 Announce Type: replace-cross Abstract: This beta technical report asks how reusable experience should be represented so that it can function as effective test-time control and as a substrate for iterative evolution. We study this question in 4.590 controlled trials across 45 scientific code-solving scenarios. We find that documentation-oriented Skill packages provide unstable control: their useful signal is sparse, and expanding a compact experience object into a fuller docume
