    I'm still wondering about this. As of now I've been able to keep the updated incumbent outside gurobi and then do the analysis with it. But would like to check why it is being cut and not accepted ...

    Do lazy constraints always cut integer solutions?

    回答済み

    Dear all, I'm currently trying to test some optimality cuts via callbacks as lazy using python. The issue I'm encountering is that the incumbent doesn't update even if the current solution doesn't ...

    Dear Marika: I understand now! I thought that having the cbSetSolution() at MIPSOL and then calling cbUseSolution() at MIPNODE would use the stored solution. Thank you very much for the clarification!

    About cbSetSolution() and cbUseSolution()

    回答済み

    Dear all, While using Python, I'm encountering a "weird" behaviour. In my code, everytime a MIP solution is found (MIPSOL) I check whether it is feasible. In case it isn't I can, heuristically, mak...

    Get the extreme ray from infeasible primal

    ユーザーの入力を待っています。

    Dear all, I'm currently solving a continuous model using the dual-simplex method with Python in order to obtain cuts that then have to be added to another MIP. This model can be optimal or infeasib...
