Hi, I'm using an IncumbentCallback. I obtain the following message(more or less):

"Control Callback will disable some MIP features..."

I know that control callback is incomptable with dynamic search. But, there are more MIP features disable when I use a control callbak?

Could it change the result of my MIP problem?

Thanks a lot!

You are correct. The use of Control callbacks (including incumbent callbacks) is not compatible with Dynamic search and hence it gets disabled in the presence of such callbacks in the program and thus the message in the node logs.

Along with this, CPLEX also turns deterministic parallelism off by default. You can however enforce the deterministic parallel mode with multiple threads by setting the ParallelMode parameter to 1.

I would recommend you to go through the following section of the CPLEX documentation:
