Hi Jaromil, sorry for the confusion. Same model, different use case. The clusters correspond to the orders set in the C++ Code. You could help me understand the following lines in the code: public...

It always shows a KeyError in which either i or j equals 0.Could it be that my clusters_nodes_depot need to include a depot in every cluster? I included the depot ("0") in both clusters and now the...

Ok I have tried printing the whole set of x variables and it becomes pretty clear that t should'nt be the 'evil' dimension. The output with a reduced T (once T = 100, later T = 50) always iterates ...

Hi Jaromil, I already started the while True loop at t = 42 as that is the value of the rounded euclidean distance between node 0 and 3 (x_0 = -5, y_0 = -5; x_3 = 32, y_3 = 15). No matter where I s...

Hi Jaromil, len(x) equals 3890 for T = 400 (maximum time). When I try to retrieve the length of the t dimension with either of your suggested methods I get a KeyError with t = 0, ,because t needs ...

Hi Jaromil, how do I print its length in each dimension? Does the Gurobi API have a method for this?   Best regards, Erik

Hi Jaromil, I tried casting it to integer but the key error stays the same (except it shows a 42 instead of the float 42.0 in the x variables):-/ Thanks Erik

Hi Eli, thank you again for your comments. The summation over \omega accidentally made it into my code and I just blindly implemented it TeX for...reasons (lazyness). Code works now. This can be cl...

Hello Eli, the code needed to be modified and doesn't work again. I tweaked the constraint mentioned above so it looks like this now: \begin{align}\sum_{t \in T} \sum_{i \in V^{\omega}} \sum_{\omeg...

Hi Eli, thank you very much. I completely forgot to include the conditional check. The x variables are defined for i != j only, so the code works now. Cheers, Erik
