public interface AspirationCriteria

extends java.io.Serializable

The optional aspiration criteria allows you to override a move's tabu status if it offers something good such as resulting in a new best solution. A null value implies no aspiration criteria.

Method Detail

public boolean overrideTabu(Solution baseSolution,
                            Move proposedMove,
                            double[] proposedValue,
                            TabuSearch tabuSearch)

Determine if the proposed tabu move should in fact be allowed because of some aspiration criteria such as being better than the previously-known best solution. The proposed move, the solution it would operate on, and the resulting objective function value are passed along with the TabuSearch itself in case there's some other data you want.
