Could you post the full example?What do you mean by "the debugging shows" the error?

Hi Giorgos, Could you please share the error you see?Your code is not directly reproducible. But if I initialize customers, vehicles, and the Gurobi model  int customers = 4;int vehicles = 5;GRB...

Hi,All solutions in the solution pool should be feasible solutions.Could you share a minimal reproducible example? Best, Marika

Hi Ankan, We can reproduce what you described. Our development team will investigate this further. We will update you then. Thanks for your patience,Marika

As the documentation of ConcurrentMIP says When the parameter is set to value n, the MIP solver performs n independent MIP solves in parallel, with different parameter settings for each. Optimizat...

If you want to check your model, we recommend using Model.write(), for example model.write("model.lp"). You can then display the lp file for example with print(open("model.lp", "r").read()). Note t...

If you want to fix (some) variables to the values given in a sol file, you can fix the upper and the lower bound to the values. This is preferable to adding constraints.If the variable names of sol...

In the definition of your constraint Q[i,c,mov] is only defined for c=1,2. But later you access for c=3. So it looks like the constraint you checked with the solution was not added to the model. Co...

Your example is not reproducible. But I think the issue is that you need to define PN as Gurobi variables as well if you want to change the values. This is not possible: A= m.addVar(vtype='B')B= 3m...
