    Pure-Python TSP heuristic utilizes Cooks Ruler Sweep Algorithm that boosts the optimization of your current design software or warehouse robot manager. No training. No compilation. No cloud. No subscription (by g4mbit5)

    Project mention: Cook's Ruler Sweep: 10k-city TSP in 17 minutes (pure Python) | news.ycombinator.com | 2025-11-19

    A 150-line pure-Python TSP heuristic that beats Nearest Neighbor by +10–13.8% on real-world geographic data — including 10,000 US cities in under 17 minutes.

    No training, no compilation, no external solvers. Just geometry and a 1.3× tolerance band.

    I built it in a 72-hour rage after hitting a wall trying to optimize an app I'm building for my cybersecurity startup.
