Hello,

I have a problem regarding the size of my model, and would like to know if it is my computer or if the model is just to big.

The statistics show, that the model got 389.497 constraints, 159.257 variables (86.392 binary, 72.648 integer) and 14.737.552 non-zero-coefficients.

The engine log shows that probing is done for 190 sec (89%), 707 sec of clique growth (52%), 30 sec for 42% of clique merging. After that the search begins and builds up a big tree with more and more nodes to search without finding a proper solution. Though the statistics show no best integer solution.

Can anyone give some tips what I could do?

Best regards
