``` Hey Product Hunt! 👋 I'm Abhishek, and I spent months trying to match LKH-3 — the TSP solver that's been the academic gold standard for 20+ years. Lambda-G gets within 0.13% on 1000-city benchmarks. It matches LKH-3 exactly on kroA100. And it beats Google OR-Tools by ~2.5%. But here's what I find most interesting: TSP isn't just about delivery trucks. The same algorithm solves: • DNA...
