Class IloSOS1

Definition file: ilconcert/ilolinear.h

This handle class represents special ordered sets of type 1 (SOS1). A special ordered set of type 1 specifies a set of variables, and only one among them may take a non zero value. You may assign a weight to each variable in an SOS1. This weight indicates an order among the variables. If you do not specify any weights to indicate order among the variables, then Concert Technology considers the order in which you gave the variables to the constructor of this set and the order in which you added variables later.

When you extract a model (an instance of IloModel) for an instance of IloCplex (documented in the ILOG CPLEX Reference Manual), it will use the order for branching on variables.

For more details about SOS1, see the ILOG CPLEX Reference and User's Manuals.

Most member functions in this class contain assert statements. For an explanation of the macro NDEBUG (a way to turn on or turn off these assert statements), see the concept Assert and NDEBUG.

IloSOS1

public IloSOS1()

This constructor creates an empty handle. You must initialize it before you use it.

IloSOS1

public IloSOS1(IloSOS1::ImplClass * impl)

This constructor creates a handle object from a pointer to an implementation object.

IloSOS1

public IloSOS1(const IloEnv env, const char * name)

This constructor creates a special ordered set of type 1 (SOS1). You must add the variables to this set for them to be taken into account.

IloSOS1

public IloSOS1(const IloEnv env, const IloNumVarArray vars, const char * name)

This constructor creates a special ordered set of type 1 (SOS1). The set includes each of the variables specified in the array vars.

IloSOS1

public IloSOS1(const IloEnv env, const IloNumVarArray vars, const IloNumArray vals, const char * name)

This constructor creates a special ordered set of type 1 (SOS1). The set includes the variables specified in the array vars. The corresponding value in vals indicates the weight of each variable in vars.
