AI-Assisted Proof: Erdős–Simonovits Conjecture Fails at Every Level

ctjlewis · x · 2026-08-02

The GitHub project EvolvingPrograms/erdos-simonovits-degeneracy provides a complete Lean 4 formalization showing the Erdős–Simonovits degeneracy conjecture fails at every level (r ≥ 2), with the sharp asymptotic law at Gibbs weight e. Completed by Claude Fable 5 and Claude Opus 5 on 2026-08-01, the project includes multiple Lean files.
