A solution found by the constraint programming solver violates breaks of vehicles. The breaks are fixed and performed. A repro is included.
It is possible to define an instance of the Vehicle Routi…

Setting aside the (somehow specific) TSP part, we support two different VRP flavors for now: CVRP and VRPTW. It was not that clear from the start but as it turned up both solving strategies share most…

We need to format classic VRPTW benchmark files to serve as a set of reference instances while developing https://github.com/VROOM-Project/vroom/issues/113.
The reference benchmarks used in the lit…
