PS: I I would like to add that I set NoRelHeurTime = 36000 s. Therefore, the time limit will not be the reason for the program termination.

Hi Jaromił, I did some testing ...I tried the partition heuristic (although I didn't expect a solution to my general memory problem, but I want to explore general properties ...). Here is the log: ...

Hi Jaromił Najman, thanks for your reply. Yes, decomposition is an option. I already have two ideas for grouping the variables reasonably. I suppose the partition heuristic with PartitionPlace incl...

Hi Jaromił Najman, I would like to come back to my problems here. I reformulated my problem (among other approaches with your help in the topic: https://support.gurobi.com/hc/en-us/community/posts/...

Hi Jaromił Najman, thanks for your explanations. I did intensive testing with the parameters, but in the end it was necessary to perform the reductions manually. And I had to set AggFill to zero (s...

Hi Jaromił, I would like to take up this topic here. I looked into section 5.3 of the specified paper and in my applications I have a lot of constraints that fit into the scheme [s * A_qS = A_rS] f...

Hi Jaromił, thanks for your reply.I already assumed that GRBaddconstr() isn't thread-safe.But as you said, that's not really a problem because I can create the arguments for the function call in pa...

Hi Jaromił, thanks again for your continuous support. I am in a(nother) testing phase of my work and it is not an actual problem to reduce the problem size for examples.I already reduced the size b...

Hi Gurobot (AI-generated response), thanks for your reply. In the meantime, I have familiarized myself with the C-API in more detail and understand how CSR & CSC are used here. With regard to the P...

Hello Jaromił, thanks for your helpful answer. I can work with the limit on the number of variables at the moment by doing some variable eliminations myself, which I would have preferred to leave t...
