All Implemented Interfaces:

Cloneable

@ALDDerivedClass
 @ALDParametrizedClass
public class MTBTermAreaDiff
extends MTBTermination

Check upon snake termination by the area within the snake.

Termination is done when the area difference of the former and the current snake is below a given fraction factor or if a maximum number of iterations is reached.

Constructor Detail

MTBTermAreaDiff

public MTBTermAreaDiff()

Default constructor.

MTBTermAreaDiff

public MTBTermAreaDiff(double _areaFraction,
                       int _maxIterations)

Constructor with area fraction below the snake iteration is terminated or if a maximum number of iterations is reached.

Method Detail

init

public boolean init(SnakeOptimizerSingle opt)

Description copied from class: MTBTermination

Initializing routine which is called once before the termination is actually used.

In this routine global parameter settings can be handled or other initialization stuff be done. The SnakeOptimizer will call this routine once before the actual use of the termination strategy. If no stuff needs to be done in advance the routine should at least return true.

Specified by:

init in class MTBTermination

Parameters:

opt - calling snake optimizer

Returns:

True if init was successful.

terminate

public SnakeOptimizer.Snake_status terminate()

Termination is done when the area difference of the former and the current snake is below a given fraction factor or if a maximum number of iterations is reached.

Specified by:

terminate in class MTBTermination

Returns:

Status of the current snake.

getAreaFraction

public double getAreaFraction()

Get area fraction.

Returns:

Area Fraction.

getMaxIter

public int getMaxIter()

Get maximum iteration count.

Returns:

Maximum Iterations.

toString

public String toString()

Description copied from class: MTBTermination

Method for short termination description name.

Specified by:

toString in class MTBTermination

clone

public MTBTermAreaDiff clone()
                      throws CloneNotSupportedException

Clones this object.

Note that the SnakeOptimizerSingle object is left null! You have to call SnakeOptimizer.initOptimizer() before using the gamma updater.

Specified by:

clone in class MTBTermination

Throws:

CloneNotSupportedException
