New AI framework boosts theorem proving with mutation-enhanced skill evolution

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SkillEvoLean, a novel framework for enhancing large language model agents in formal theorem proving. This method employs mutation-enhanced skill evolution, which updates both a high-level solving policy and reference knowledge. When standard methods fail to find successful trajectories, SkillEvoLean uses mutation to sample mathematical concepts and generate new skill candidates. Tested with GPT-5.5 on benchmarks like MiniF2F and PutnamBench, as well as the IMO 2025 and USAMO 2026 problems, SkillEvoLean achieved significantly higher proof success rates compared to baseline methods. AI

IMPACT Enhances AI capabilities in formal theorem proving, potentially accelerating mathematical discovery and formal verification.

    SkillEvoLean: Mutation-enhanced skill evolution for Lean provers

    arXiv:2610.01799v1 Announce Type: new Abstract: Skill evolution offers a promising way to improve large language model agents without updating their parameters, but its use in formal theorem proving remains underexplored. Existing methods mainly target natural-language reasoning,…
