Procedure GenerateCut(Arow, local)

GenerateCut

The procedure GenerateCut adds a cut during the solution process of a mixed integer program.

GenerateCut(
     Arow,        ! (input) a scalar value
     [local]      ! (optional, default 1) a scalar binary expression
     )

Arguments

Arow

A scalar reference to an existing row name in the model.

local

A scalar binary value to indicate whether the cut is valid for the local problem (i.e. the problem corresponding to the current node in the solution process and all its descendant nodes) only (value 1) or for the global problem (value 0).

Return Value

The procedure returns 1 on success, or 0 otherwise.

Note

  • This procedure can only be called from within a CallbackAddCut callback procedure.

  • A CallbackAddCut callback procedure will only be called when solving mixed integer programs with CPLEX, GUROBI or ODH-CPLEX.
