Scaling up Multi-Turn Off-Policy RL and Multi-Agent Tree Search for LLM Step-Provers

ICML 2026poster

The integration of Large Language Models (LLMs) with automated theorem proving has shown immense promise, yet is constrained by challenges in scaling up both training-time reinforcement learning (RL) and inference-time compute. This paper introduces BFS-Prover-V2, a step-level theorem proving system…

BFS-Prover: Scalable Best-First Tree Search for LLM-based Automatic Theorem Proving

ACL 2025long

Recent advancements in large language models (LLMs) have spurred growing interest in automatic theorem proving using Lean4, where effective tree search methods are crucial for navigating the underlying large proof search spaces. While the existing approaches primarily rely on value functions and/or…

AutoPrune: Automatic Network Pruning by Regularizing Auxiliary Parameters

NeurIPS 2019poster

Reducing the model redundancy is an important task to deploy complex deep learning models to resource-limited or time-sensitive devices. Directly regularizing or modifying weight values makes pruning procedure less robust and sensitive to the choice of hyperparameters, and it also requires prior kno…
