Show HN: Formally verified polygon intersection – Opus 4.8 oneshots, prev failed
A developer has created a formally verified implementation of a polygon intersection algorithm using the Lean 4 proof assistant. The project demonstrates how AI agents can now assist in generating complex, mathematically verified code in a single step.
Why it matters
This represents a milestone in software engineering, showing that AI can be used to produce high-assurance, bug-free code for critical computational tasks.
To my knowledge, this is the first formally verified implementation of an intersection algorithm for polygons. (Also compare with Related work )
