Carl Baier commented,
Jaromił Najman Well its weird since isnt infeasible but i just cant compute the duals. Any further ideas why that can be?

Carl Baier commented,
Jaromił Najman I did some testing and noticed something strange. I copied the Demand_Dict once and multiplied all values by 0.1. If I now use the constraint: def generateConstraints(self): for ...

Carl Baier commented,
Jaromił Najman Sure. I updated the code and here are all the possible logs produced (lo0.txt , log1.txt and log2.txt). I guess log1.txt indicates the problem, stating: Continuous model is nonconv...

Carl Baier commented,
Jaromił Najman Thanks. I dont know why it should be quadratic nonconvex now, as the new constraint is like the same as the original demand one. I tried the NonConvex with values of 1 and 2, but ne...

Carl Baier commented,
Jaromił Najman Its me again. I have been able to expand my model very well in the last few weeks and everything is working so far. Many thanks again. But now I have experimented a bit with my cod...

Carl Baier commented,
Jaromił Najman Thank you, I solved it by saving the value of the last iteration performed in a variable and then removing all variables with the index \(r>\)last_itr with remove(). I still have a q...

Carl Baier commented,
Jaromił Najman Thanks. Is there any quick way to collect all those variables?

Carl Baier commented,
Jaromił Najman Are there any start guides that can help with the implementation of BranchnPrice? And over the weekend I thought of two more questions. 1) Is it possible to delete all the unused...

Carl Baier commented,
Jaromił Najman Nevermind, I swapped the values of the classic model (without CG) and the column generation. As a result, the column generation performs just as well in some instances as the simple...

Carl Baier commented,
Jaromił Najman Thank you very much. It's finally working. I have now adapted these two functions, and now it works. It also spits out the same optimal values \(motivation\) after finalSolve() as i...
