    Hi,

    How can i print out cuts that CPLEX is applying while solving ILP? (Concert, C++)

    Thank you in advance.

    Best regards,

    Vlad

    You can obtain the cuts using the C callable library and a callback, but even this is an ugly task.

    Thomas is right. The only API that allows you to figure out which cuts CPLEX added is the callable library API (the C API).

    This issue has been discussed many times here. Just search the Forum for more information. You will also find instructions about how to do that in the C API.
