New LEVER algorithm optimizes AI proof search for cost and quality

Researchers have developed LEVER, a novel proof search algorithm designed to optimize proofs not just for correctness but also for user-defined objectives like simplicity, purity, and computational cost. LEVER integrates these objectives into the search process by scoring partial proofs over AND/OR graphs, combining realized values with predictions for open subgoals. This approach allows for programmable optimization during search, leading to significant improvements in efficiency and quality. On the PutnamBench benchmark in Lean 4, LEVER reduced computational cost by 34% while increasing the solve rate from 80% to 96%, and also showed improvements in reducing topical impurity and proof length. AI

IMPACT Enhances AI's ability to find optimal mathematical proofs, potentially accelerating research in formal verification and theorem proving.

    LEVER: Adaptive Cost-Aware Proof Search Over AND/OR Graphs

    arXiv:2610.11862v1 Announce Type: new Abstract: Mathematicians value proofs for more than correctness: among correct proofs, simplicity, purity and the computational cost of finding them vary widely. Yet LLM-powered theorem provers largely search for any correct proof, and improv…
