All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable

public class FloatGene

extends GpTreeNode

Represents a float value with some min and max value. Evaluates between -1 and 1 in this base class, but override getMin and getMax to change the type of Number this represents (may also need to configure FloatGaussianRangeMutator).

Method Detail

getReturnClass

public java.lang.Class getReturnClass()

Specified by:

getReturnClass in class GpTreeNode

Returns:

the class this gene returns on evaluation

getMin

public java.lang.Number getMin()

Note this is called from the constructor to initialise the value.

getMax

public java.lang.Number getMax()

Note this is called from the constructor to initialise the value.

setValue

public final void setValue(java.lang.Number value)

getValue

public java.lang.Number getValue()

evaluate

public java.lang.Object evaluate(Phenotype phenotype)

Description copied from class: GpTreeNode

Evaluate this expression in the context of the passed Phenotype.

Specified by:

evaluate in class GpTreeNode

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getMutators

protected java.util.SortedMap getMutators()

Description copied from class: GpTreeNode

Provides a SortedMap of GpMutators with their probabilities (Doubles between 0.0 and 1.0) so that #mutate(float) can choose one to do a mutation. The map needs to look like:

0.1

a GpMutator instance with 10% chance of being used

0.2

a different GpMutator instance with 10% chance of being used

1.0

a GpMutator instance with 80% chance of being used

Load from configuration properties. [getClass().getName()].mutator.class.0 and optionally [getClass().getName()].mutator.probability.0 using: Configuration.getInstance().getInstancesProbabilities(getClass().getName() + ".mutator");

Overrides:

getMutators in class GpTreeNode

Returns:

SortedMap of probability vs mutator class, or null if no mutators for this gene

See Also:

GpTreeNode.getMutators()

getParameterClasses

protected java.util.List getParameterClasses()

Specified by:

getParameterClasses in class GpTreeNode

Returns:

List of the Classes that this gene expects to evaluate against

See Also:

GpTreeNode.getParameterClasses()

getParameterGene

public GpTreeNode getParameterGene(int index)

Specified by:

getParameterGene in class GpTreeNode

Returns:

the gene at the passed index, may be null

See Also:

GpTreeNode.getParameterGene(int)

setParameterGene

public void setParameterGene(int index,
                             GpTreeNode gene)

Specified by:

setParameterGene in class GpTreeNode

Parameters:

index - the index of the gene to replace

gene - the gene to replace with

See Also:

GpTreeNode.setParameterGene(int, GpTreeNode)

clone

public java.lang.Object clone()

Override to clone the Number value field.

Overrides:

clone in class GpTreeNode
