arXiv:2606.15972v1 Announce Type: new Abstract: With large language models (LLMs) increasingly applied to mathematical reasoning, formal proof assistants such as Lean can be leveraged to verify reasoning outputs with machine-checkable rigor, enabling use cases such as answer selection in test-time scaling with K sampled candidate answers. However, employing Lean requires that LLM outputs, originally in natural language, first be formalized. Existing Lean-based answer-selection work uses an autoformalization model to generate a formal statement in Lean for each candidate answer independently, i
The increasing adoption of LLMs for mathematical reasoning creates an immediate need for robust formal verification methods to ensure accuracy and trustworthiness.
This development enhances the reliability and trustworthiness of AI systems in critical domains requiring rigorous mathematical proof, expanding their applicability.
The efficiency of integrating formal proof assistants like Lean with LLMs for answer selection is significantly improved, streamlining the verification process.
