CPXdelsetsos

Description

The routine CPXdelsetsos is used to delete a group of special ordered sets (SOSs) from a CPLEX problem object.

The routine returns a zero on success, and a nonzero if an error occurs.

int CPXdelsetsos (CPXCENVptr env, CPXLPptr lp, int *delset);

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

A pointer to a CPLEX problem object as returned by CPXcreateprob().

An array indicating the SOSs to be deleted. The routine CPXdelsetsos() deletes each SOS j for which delstat[j] = 1. The deletion of SOSs results in a renumbering of the remaining SOSs. After termination, delstat[j] is either -1 for SOSs that have been deleted or the new index number that has been assigned to the remaining SOSs.

The delstat array must have at least CPXgetnumsos(env,lp) elements.

status = CPXdelsetsos (env, lp, delstat);
