New LLM methods boost verified code generation with integrated planning and proof search

Researchers have developed new methods for verified code generation, where large language models (LLMs) produce both executable programs and machine-checkable proofs of correctness. The first approach, P$^{3}$, integrates program and proof planning to improve efficiency and effectiveness, achieving higher solve rates and reducing costs on benchmarks like Lean4Commit0. The second method, Goedel-Code-Prover, employs hierarchical proof search in Lean 4, decomposing complex verification goals into simpler subgoals to achieve a 62.0% prove success rate on its benchmarks. AI

    P$^{3}$: Joint Program-and-Proof Planning for Verified Code Generation

    arXiv:2608.09277v1 Announce Type: new Abstract: Verified code generation asks a large language model (LLM) to generate both an executable program and a machine-checkable proof that the program meets a formal specification, promising software that is correct by construction. The d…
