Does Gurobi have lift and project cut? I found a relax and lift cut, but can't find any interpretation about the cut, are they the same?

  Hi,

  Gurobi currently does not have lift and project cuts but we are working on it.

  Relax and Lift cuts first construct a relaxation of an LP row by  fixing variables to its bounds and then try to lift binaries into the cut.

  Best regards,
