- TLDR:While surface prompting fails to recover diversity, entrance-targeted interventions succeed: late-layer parameter interpolation with early checkpoints increases solution coverage by 37% at no loss in pass@1 and late-layer parameter interpolation with early checkpoints increases solution coverage by 37% at no loss in pass@1.

- 标题中文:锁于入口,开于内里:RLVR 收窄解空间的位置
- TLDR中文:表面 prompting 未能恢复多样性,而针对入口的干预则成功:使用早期 checkpoint 的 late-layer parameter interpolation 在不损失 pass@1 的情况下将解的覆盖度提高了 37%。
