Method Details

canHandle

public boolean canHandle(ParentComparisonPolicy parentComparisonPolicy)

Description copied from interface: ParentComparisonHandler

Determines whether this handler can process the given parent comparison policy.

This method allows the handler registry to determine which handler is appropriate for a given comparison policy type, enabling polymorphic behavior in the crossover process.

Specified by:

canHandle in interface ParentComparisonHandler

Parameters:

parentComparisonPolicy - the comparison policy to check

Returns:

true if this handler can process the policy, false otherwise

compare

public ChosenOtherChromosome compare(ParentComparisonPolicy parentComparisonPolicy,
 NeatChromosome first,
 NeatChromosome second,
 int fitnessComparison)

Description copied from interface: ParentComparisonHandler

Compares two parent chromosomes and determines which should be chosen for preferred inheritance.

This method analyzes the two parent chromosomes and their relative fitness to determine which parent should be considered "chosen" (typically the fitter parent) and which should be "other" for the purposes of biased gene inheritance during crossover.

The fitness comparison parameter provides the result of comparing the parents' fitness values: positive if first is fitter, negative if second is fitter, zero if equal.

Specified by:

compare in interface ParentComparisonHandler

Parameters:

parentComparisonPolicy - the comparison policy defining the comparison strategy

first - the first parent chromosome

second - the second parent chromosome

fitnessComparison - result of fitness comparison (positive: first fitter, negative: second fitter, zero: equal)

Returns:

ChosenOtherChromosome containing the chosen parent and other parent
