Hi David, I think the problem with this approach is that any minimized flow value with 0 < flow[i, j].X < 5  leads to a lower bound on the capacity capacity[i, j].LB == 5 since capacity values bet...

Hi David, thanks for your fast response. Only that I don't just allow discrete diameters , but a continuous range. (In my case: capacity = diameter, as I assume them to be linearly dependent on eac...

Hi David, here is the working code: nodes = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40...
