int GRBfixmodel ( GRBmodel *model,
    GRBmodel **fixedP )

Create the fixed model associated with a MIP model. The MIP model must have a solution loaded (e.g., after a call to GRBoptimize). In the fixed model, each integer variable is fixed to the value that variable takes in the MIP solution.

Return value:

A non-zero return value indicates that a problem occurred while creating the fixed model. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.


model: The MIP model (with a solution loaded).

fixedP: The computed fixed model.

Example usage:

  GRBmodel *fixed;
  error = GRBfixmodel(model, &fixed);
