Hi,
I want to force the VRP solver to assign all orders at any cost; are there any ways to do that? Furthermore, I have a set of eligible routes constructed by planners and when I give it to the VRP solver, it cannot even find a feasible solution. I do not know why. There should exist at least a feasible solution; however, the VRP solver cannot find one.
There are several reasons a solve could be infeasible. Could you give some details about what you are trying to model and the parameters you have set?
