hi
when i run my mip model, the model status is code 8: integer solutions; however when I set optcr to 0 the model turn into optimal. in this situation can i assume that my model is global optimal?
Yes, you can assume that the solution is globally optimal.

Sorry, one more question. Is it possible that if I set optcr=0, the model doesn’t turn to optimal? In other words, does setting optcr=0 turn the integer solutions to optimal in any cases?
