“I didn't consider SAT solvers to be AI, but searching for "ortools" points to which has a big "Google AI" indicator on it. Who cares, I thought. But certain managers are now very keen on making a lot of noise about just how effectively their teams are using AI. So I took my four…”

Using OR-Tools CP-SAT for Scheduling Problems

Mapping my walks with OSRM and Rust

“I’ve been playing around with a similar project and it surprised me how hard map matching actually is. I’ve also been using OSRM, but no matter how I tweak the settings, it never gets it 100% right. Some examples: the GPS error is often more than the distance between a road and…”

“Hello, I set up a [Krill Test Environment]( and added the custom tal into the tals/ folder for Routinator. I read that standard Routinator with `rustls` throws an error for self-signed certificates (CAUsedAsEndEntity) so I compiled Routinator with `native-tls` instead and ran…”

reproducibility of results

“Running my CVRP script multiple times with the same input data lead to results, which differ almost all the time. As I need reproducible results the solution should always look the same. If this is the initial solution: 1: ['Source', '11', '3', '5', '9', '6', 'Sink'], (III) 2:…”
