Xpress solver freezes when using addmipsol
I have run my code, which includes adding heuristic solutions at each leaf node of the branch-and-bound tree. The added solution is feasible and accepted by the solver. However, at a certain point, t...
Hi, I set the time limit to half an hour and observed that the number of nodes remained at 89k. This suggests that there might be a freeze occurring somewhere. I have refactored my code to avoid using global variables, and the problem has disappeared. I believe this might have been the cause of the freeze. Thank you for your investigation.
