Class IlcIntSelectI

Solver lets you control the order in which the values in the domain of a constrained variable are tried during the search for a solution.

This class is the implementation class for IlcIntSelect, the class of the object that chooses the value to try when the constrained variable under consideration is a constrained integer variable (that is, an instance of IlcIntVar).

The virtual member function in IlcIntSelectI chooses a value in the domain of the constrained integer variable under consideration.

To define new selection criteria, you can define a subclass of IlcIntSelectI. If those criteria can be expressed by an evaluation function, then you can use the predefined subclass IlcIntSelectEvalI for that purpose.

This constructor creates an implementation object.

As this class is to be subclassed, a virtual destructor is provided.

This virtual member function returns one of the values of the domain of the constrained integer variable var. Its default implementation for the class IlcIntSelectI returns the minimum of the domain.
