Dear Researchers,
I hope this question finds you doing well.
I have coded an MIP model on Cplex, but when I run it, it gives a relaxed solution. However, the model has a global solution on another solver. I guess that I have to modify the run setup in Cplex to force Cplex to search for the global solution.
Best Regards,
Mahmoud
Dear Mahmoud,
I suggest you CPLEX V12, it may be that your solution to your problem is simple.
CPLEX Optimizers V12.6.0 global solution of nonconvex QP, CPLEX now can find globally optimal solutions whether the model.
Please see the following links:

Dear Dr Mohamed,
Thank you very much for your answer.

Dear Mahmoud
Make sure that you coded the model correctly, relaxed solution means that solution is infeasible. you can check conflict and relaxation windows in cplex to see the reasons for relaxation.
