    Hi,

    During model presolve and manipulation of rows/columns, we call a "learned cut" a cut, which has been found incidentally while executing some presolve procedure. In this case the word "learned" rather stands for "remember", because we then remember these additional cuts and add them to the problem. These cuts can theoretically be found in any type of problem as they are not specific to any model structure. You cannot tune these cuts individually, i.e., you cannot tell Gurobi to find more of these cuts. There is no reference about this type of cuts.

    Best regards,
    Jaromił
