Formal theorem proving research explores verifier feedback effectiveness

By PulseAugur Editorial · [1 sources] ·

Researchers have investigated the effectiveness of verifier feedback in formal theorem proving, specifically examining how models learn from failed attempts. Their experiments, conducted on Lean theorem proving problems using Qwen3.6-27B and DeepSeek-Prover-V2-7B models, revealed that while showing a model its failed proof can lead to increased copying, providing the corresponding compiler error can mitigate this loss. However, the benefits of correct diagnostics were found to be weaker without the failed proof, and no tested feedback condition established a significant advantage over simple resampling or sequential repair within a fixed token budget.

    Repair, Retry, and the Cost of Hindsight: Verifier Feedback in Formal Theorem Proving

    arXiv:2610.22698v1 Announce Type: new Abstract: Verifier-guided self-repair conditions a model on feedback from failed attempts before it tries again, without weight updates. Yet two findings in prior work are in tension: verifier feedback can improve repair of failures, but self…
