  1. BFS-Prover: Scalable Best-First Tree Search for LLM-based Automatic Theorem Proving (2025 · 49 citations)
    Proof search in Lean4 involves a huge space of possible tactics, so automated provers have mostly relied on MCTS and learned value (critic) models.
  2. Scaling up Multi-Turn Off-Policy RL and Multi-Agent Tree Search for LLM Step-Provers (2025 · 7 citations)
    The paper tackles two linked bottlenecks in LLM-based theorem proving for Lean4. In training, reinforcement learning tends to stall after early gains. At inference, the space of possible tactics grows explosively. The authors present BFS-Prover-V2, an open-source step-level prover that treats proving as a Markov…
