Cutting planes

    The comment : "Gurobi generates these cuts in the presolved model space. " is referring to the presolved model - which has different rows and columns from the original model. 

    The cuts generated in branch and bound are cuts on the presolved model, not the original model.

    I hope that helps.

    Thank you for your reply, Gwyneth! That clarifies it. 

    Would you maybe be able to also help me with the following: I understand that it is not possible to extract these cutting planes. However, would it be possible to extract where the cutting planes are generated by the solver? And if so, is there also a way to do this without the use of callback functions? 

    Thank you. 

    Best,

    Noortje
