public interface Variable
extends Serializable

Interface for decision variables. This interface ensures independent copies of decision variables can be constructed.

Method Summary

Variable

copy() Returns an independent copy of this decision variable.

Method Detail

copy

Variable copy()

Returns an independent copy of this decision variable. It is required that x.copy() is completely independent from x. This means any method invoked on x.copy() in no way alters the state of x and vice versa. It is typically the case that x.copy().getClass() == x.getClass() and x.copy().equals(x).

Returns:

an independent copy of this decision variable
