Class DesiredMaximizationFitness

java.lang.Object
  net.sourceforge.cilib.bioinf.sequencealignment.DesiredMaximizationFitness

All Implemented Interfaces:

Serializable, StoppingCondition, Cloneable

public class DesiredMaximizationFitness
extends Object
implements StoppingCondition

This class serves as a crude implementation of a stopping condition that forces the optimizer to stop whenever a arbitrary fitness has been reached. Handy to measure how fast an optimizer gets to a goal fitness. Prevents wasting computational power and time when optimal solution has already been found.

Method Detail

getClone

public DesiredMaximizationFitness getClone()

Description copied from interface: Cloneable

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface StoppingCondition

Specified by:

getClone in interface Cloneable

Returns:

An exact clone of the current object instance.

Object.clone()

getFitness

public double getFitness()

setDesiredFitness

public void setDesiredFitness(double desiredFitness)

getPercentageCompleted

public double getPercentageCompleted()

Description copied from interface: StoppingCondition

Determines the percentage complete for the associated algorithm.

Specified by:

getPercentageCompleted in interface StoppingCondition

isCompleted

public boolean isCompleted()

Description copied from interface: StoppingCondition

Determines whether the stopping condition has been satisfied (equivalent to StoppingCondition.getPercentageCompleted() == 1.0 but may be more efficient).

Specified by:

isCompleted in interface StoppingCondition

Returns:

true when condition is satisfied, false otherwise

setAlgorithm

public void setAlgorithm(Algorithm algorithm)

Description copied from interface: StoppingCondition

Sets the algorithm that this stopping condition should be applied to. Called by Algorithm.addStoppingCondition(StoppingCondition). This ensures that any down casting necessary is done only once, when the stopping codition is added to an alogorithm (as apposed to after each iteration).

Specified by:

setAlgorithm in interface StoppingCondition

Parameters:

algorithm - The applicable Algorithm.

getQuitAnywayAfterIterations

public int getQuitAnywayAfterIterations()

setQuitAnywayAfterIterations

public void setQuitAnywayAfterIterations(int quitAnywayAfterIterations)
