    Hi Jihye,

    As commented in your other post, user cuts/lazy constraints can be useful only at a certain stage of the optimization process and then dropped later such that they do not occur in the "Cuts statistics". Thus, applying a callback function can certainly change the solution path in a positive or negative way. In your case, applying user cuts improves the performance of the optimization.

    Hi Jaromił,

    My test results are being interpreted quite positively thanks to your answers.
    I desperately needed an answer, thank you very much.

    Best regards,
    Jihye
