Currently, the service duration of jobs that happens to be in the same location is calculated with the formula:
service_duration_of_jobs = #jobs * step.service
For example, The service time of …

We store various incompatibilities between vehicles and jobs (based on skills and other constraints) for constant-time lookup through `Input::vehicle_ok_with_job`. This *used to* allow early aborts fo…

One of my customers often transports some pallets on the second and even third "layer". Usually loads on different layers goes to different destinations. I cannot think of good limit schema with curre…

That's cool ! I also tested the Solomon case with the 50 first vertices and with the LP version of the sub problem and was able to find the solution of the benchmarks. This is reassuring !The solution…

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…

A bit of profiling on current master (e.g. on solomon instances) shows that most of the local search time - that is most of the overall time - is spent in various operators validity checks, while com…
