Automating Formal Verification with Agent-Guided Tree Search

arXiv:2605.27485v1 Announce Type: cross Abstract: Formal verification offers a path to provably correct software, but writing verified code remains expensive enough that the technique is rarely used in production. Recent large language models can accelerate this work, and recent benchmarks measure their ability to translate specifications into code and machine-checked proofs of correctness. This thesis evaluates the state of such LLM-driven verified-code generation ("vericoding") in Lean and develops search-based methods for improving verification performance. We first reproduce a subset of th

Why this matters
Why now

The proliferation of powerful large language models and increasing demand for reliable software in critical systems creates fertile ground for advanced verification techniques.

Why it’s important

Improving the automation and accessibility of formal verification could significantly enhance software reliability and security, particularly in sensitive applications.

What changes

The barrier to entry for developing provably correct software is lowered, moving formal verification from a niche academic pursuit to a more scalable industry tool.
