int GRBdelsos ( GRBmodel *model,
    int numdel,
    int *ind )

Delete a list of Special Ordered Set (SOS) constraints from an existing model. Note that the SOS constraints won't actually be removed until the next call to GRBoptimize or GRBupdatemodel.

Return value:

A non-zero return value indicates that a problem occurred while deleting the constraints. 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 model to modify.

numdel: The number of SOSs to remove.

ind: The indices of the SOSs to remove.

Example usage:

  int first_four[] = {0, 1, 2, 3};
  error = GRBdelsos(model, 4, first_four);
