Lean Programming Language
Lean is a theorem prover and programming language that enables correct, maintainable, and formally verified code.

Seed-Prover
Formal languages like Lean enable automatic verification, making them advantageous for reinforcement learning (RL) through Lemma-Style Proving: proving intermediate lemmas first → utilizing them for main theorems, and Iterative Refinement: iteratively improving proofs using Lean feedback, self-summarization, and leveraging previous proofs.

수학, 인공지능, 그리고 형식화 [2]: 증명의 형식화와 인공지능
앞에서 우리는 인공지능을 어떻게 수학 연구에 활용할 수 있는지에 대해서 알아보았습니다. 이번 편에서는 최근에 떠오르고 있는 증명의 형식화formalization에 대해서 알아보고, AI, 특히 LLM을 활용한 수학 연구에서의 형식화의 역할과 형식화에 있어서의 AI의 역할과 주의할 점에 대해서 알아보면서 이 시리즈를 마치고자 합니다. AI가 증명을 했다고 주장하는데, 확실한가요? 앞서 언급했듯이 ChatGPT Pro나 Gemini Deep Think 등 최전선에 있는…

Palomar – a registry of Lean verified mathematics
In recent months there has been a proliferation of AI-generated proofs of various old and new results, some of which have been formalized in the proof assistant language Lean. However, checking tha…
