Dear All,
I would like to know whether it is possible to use or-tools to solve a version of the orienteering problem with time windows and chosen compulsory vertices. I have looked through the guid…

Hello there,
First, thank you for the great work on the vrp solver. It is quite easy to use and really fast in many cases.
But I just came across this weird issue, that the route seems to be fea…

Hello,
I am running a pretty large VRPTW instance. And from time to time, I came across this issue.
It seems the model stops running after showing this message.
For example,
"Bucket graph for G_…

The execution hangs and does not respond to `SIGINT` (was sent in 5min), had to `SIGKILL` after another 5 minutes.
Version: 1.22.1
Command:

Thanks for awesome library.
Currently I try to solve CVRP with vehicles that can return multiple times to depot. For example, we have one vehcile. Max weight of vehicle is 1000kg and we have two orde…

Dear Authors,
It seems that there is a bug in https://github.com/google/or-tools/blob/master/ortools/constraint_solver/samples/vrp_pickup_delivery.py.
In the print_solution function, it seems th…

There are many repositories solving VRP. To be convincing as SOTA solver, we should add a (summary) results table in README including running time and gap to BKS.
Some options for VRPTW:
- Solomon…

Hi, am working of a VRP problem with capacities and time window constraints, i wonder what does it mean when we see "RCSP solver WARNING : the best solution could not be retrieved" .

Hi @reinterpretcat , This project has been amazing with the variety of problem solving it offers and i've been really loving it.
I have been using the python pip package and was wondering if it was…
