Class TargetFitnessTerminator<T>

java.lang.Object

org.cicirello.search.evo.TargetFitnessTerminator<T>

Type Parameters:

T - The type of object under optimization.

All Implemented Interfaces:

TerminationStrategy<T>

public final class TargetFitnessTerminator<T>
extends Object
implements TerminationStrategy<T>

TerminationStrategy that terminates an evolutionary algorithm if a solution with a target fitness value (or better) is found.

Constructor Details

TargetFitnessTerminator

public TargetFitnessTerminator(double targetFitness)

Initializes the TerminationStrategy

Parameters:

targetFitness - the target fitness. Note that this is the target fitness value and not a target for the objective function you are optimizing, which may or may not be the same thing depending upon how you have configured the evolutionary algorithm

Method Details

terminate

public boolean terminate(TerminationStrategy.ExecutionState<T> state)

Description copied from interface: TerminationStrategy

Predicate method to determine whether or not to terminate the current run of the evolutionary algorithm.

Specified by:

terminate in interface TerminationStrategy<T>

Parameters:

state - the state of the evolutionary algorithm prior to the start of a generation

Returns:

true if and only if the evolutionary algorithm should terminate
