Method Detail

clone

public SamplingScoreBasedClassifierParameterSet clone()
                                               throws CloneNotSupportedException

Description copied from class: ParameterSet

Creates a full clone (deep copy) of this ParameterSet. As a convenience-method the user can use fillWithStandardFieldsForClone(ParameterSet) on a newly created instance of a subclass of ParameterSet to obtain a clone/copy of all standard member variables (those already defined in ParameterSet) in the passed ParameterSet. Using this method, the cloning process becomes merely three-step:

• Create a new instance of your subclass of ParameterSet, most likely with an empty constructor or the one taking just the instance class.
• Call this.fillWithStandardFieldsForClone on this instance.
• Return the instance.

This method fulfills the conventions of Object's method Object.clone().

Overrides:

clone in class SequenceScoringParameterSet

Returns:

a deep clone/copy of this ParameterSet

Throws:

CloneNotSupportedException

getNumberOfStarts

public int getNumberOfStarts()

getNumberOfTestSamplings

public int getNumberOfTestSamplings()

Returns the number of samplings between checks for the stationary phase

Returns:

te number of samplings

getNumberOfStationarySamplings

public int getNumberOfStationarySamplings()

Returns the number of samplings steps in the stationary phase

Returns:

the number of steps

getFreeParameters

public boolean getFreeParameters()

Returns true if only free parameters shall be used

Returns:

if only free parameters shall be used

getAdaptVariance

public boolean getAdaptVariance()

Returns true if the sampling variance shall be adapted to the size of the event space of a random variable

Returns:

if the sampling variance shall be adapted
