Lean-backed verifier solves 1007 competitive programming proofs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach to automatically generate proofs for competitive programming problems using a verifier backed by the Lean 4 programming language. This system successfully proved all 1325 theorems across 1007 VeriContest problems, a benchmark designed to test proof generation capabilities. While frontier models like Claude Opus 5.5 achieved a 13.95% success rate on the first attempt, the Lean-backed verifier proved 70% of theorems on the first iteration, with the entire set completed in under 32 hours at a cost of $1.17 per proof.

IMPACT Demonstrates a more efficient and cost-effective method for automated proof generation compared to current frontier LLMs.

    Solving VeriContest with a Lean-Backed Rust Verifier

    arXiv:2610.03994v2 Announce Type: replace-cross Abstract: VeriContest is a benchmark of 1007 competitive-programming problems in Rust, each with a Verus specification, a judge-accepted solution, and a Verus proof. Its authors report that proof generation is the bottleneck for fro…
