Hi,

I have found in the (Python) API to add cuts during the solving process, but I cannot find a way to retrieve the cuts that were added in the global cut table after the model is solved.

How can I find which cuts were generated?

Thanks

  Hi Josep,

  The cuts are generated in terms of the presolved model. Because Gurobi does not allow access to the presolved model, you also cannot extract the cuts that were generated.

  Hi Matthias,

   

  I have a similar problem.

  If I close presolve, could I retreive those cuts?

  Hi Fan,

  It's unfortunately not possible to get the generated cuts - even when disabling presolve.

  Cheers,
  Matthias
