Hi Mario, thank you for your pointers. I'll have a look at Depth-First-Search procedures and see if I'm able to implement it as such. Best Regards, Michael Renner

Hello Mario, Thank you for your answer. First of all, which of the constraints and/or variables of the formulation from the other post did you remove such that you get integer solutions in the MIP...

Hi Mario, I will now run the automatic tuning tool again to see from which parameters i can benefit to find solutions for different model sizes, as well as what a reasonable MIPGap is. I already ha...

Hello Mario, I revisited the lp file of my model and noticed I made a mistake when adding one of your constraints: sum_{j \in J} x_{ijk} <= y_i, for all i \in I, k \in K. After correctly implemen...

Hi Mario, thank you for your suggestions. As you might have noticed I am just beginning to learn about mixed integer linear programming, so I am grateful for the pointers. The fact that you have t...

Hello Mario, first of, thank you for your timely response. Do you have an idea whether the optimal value for the second model is nearer to the bound of 161 or nearer to the current incumbent of 20...
