GRBdelsos
| int | GRBdelsos ( | GRBmodel | *model, |
| int | numdel, | ||
| int | *ind ) |
Delete a list of Special Ordered Set (SOS) constraints from an existing model. Note that, due to our lazy update approach, the SOS constraints won't actually be removed until you update the model (using GRBupdatemodel), optimize the model (using GRBoptimize), or write the model to disk (using GRBwrite).
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.
Arguments:
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);
