AI Cracks 12-Year-Old Math Puzzle Autonomously
18 Apr
Summary
- Dual AI system solved a 12-year-old algebra conjecture autonomously.
- Rethlas explores strategies, Archon formalizes proofs for Lean 4.
- AI performed tasks faster than humans, with minimal intervention.

A new dual-agent AI system developed by Peking University has successfully solved Anderson's conjecture, an algebra problem posed in 2014. The AI system independently tackled the 12-year-old puzzle over 80 hours, a feat researchers noted required essentially no human intervention for the problem-solving or proof formalization.
The system utilizes Rethlas to explore mathematical strategies and Archon to transform potential proofs for the Lean 4 verifier. This framework bridges natural language reasoning with formal machine verification.
