    Hi,

    It can happen (due to multithreading) that the same solution comes up multiple times since newly added lazy cuts might not be synchronized among the threads yet. You have to make sure that you always add a lazy cut if the solution is infeasible even if you did it already before.
    So what you are seeing is expected behavior.

    Best regards,
    Mario
