A chooser of integer values is an object that is used
to define search strategies. In particular, this class makes it possible to
design custom value selection by redefining the pure virtual
function
IloInt IloIntValueChooserI::choose(IloCPEngine cp, IloIntVarArray x, IloInt index)
| Method Summary | |
|---|---|
public virtual IloInt | choose(IloCPEngine cp, IloIntVarArray x, IloInt index) |
public | IloIntValueChooserI(IloEnv env) |
public | ~IloIntValueChooserI() |
| Method Detail |
|---|
This constructor creates an implementation of a value chooser.
It must be called in the constructor of any sub-class of
IloIntValueChooserI.
As this class is abstract, a virtual destructor is provided.
This pure virtual function must be defined to choose a value
for the variable x[index].
The variable x[index] has been selected
from the array x at an earlier stage. The selected value must
be returned by the method. The array x is given to such a method
because some value selection strategies may need the full array
of variables to perform a selection.
