| Java Source File Name | Type | Comment |
| AllImplTests.java | Class | |
| AveragingCrossoverOperator.java | Class | The averaging crossover operator randomly selects two Chromosomes from the
population and "mates" them by randomly picking a gene and then swapping that
gene and all subsequent genes between the two Chromosomes. |
| AveragingCrossoverOperatorTest.java | Class | Tests the AveragingCrossoverOperator class. |
| BestChromosomesSelector.java | Class | Implementation of a NaturalSelector that takes the top n chromosomes into
the next generation. |
| BestChromosomesSelectorTest.java | Class | Tests the BestChromosomesSelector class. |
| BooleanGene.java | Class | A Gene implementation that supports two possible values (alleles) for each
gene: true and false.
NOTE: Since this Gene implementation only supports two different
values (true and false), there's only a 50% chance that invocation
of the setToRandomValue() method will actually change the value of
this Gene (if it has a value). |
| BooleanGeneTest.java | Class | Tests the BooleanGene class. |
| BulkFitnessOffsetRemover.java | Class | Takes away the fitness offset of the population to evolve.
The fitness function values of the population of
org.jgap.IChromosome instances will start from a minimum of 1 afterwards.
The removal of an offset in the fitness values of a population strengthens
the "survival of the fittest" effect of a selector that performs selection
upon fitness values. |
| BulkFitnessOffsetRemoverTest.java | Class | Tests for the BulkFitnessOffsetRemover class. |
| CauchyRandomGenerator.java | Class | Cauchy probability density function (cumulative distribution function). |

| ChainOfSelectorsTest.java | Class | Tests the ChainOfSelectors class. |
| ChromosomePool.java | Class | Provides a pooling mechanism for Chromosome instances so that
discarded Chromosome instances can be recycled, thus saving memory and the
overhead of constructing new ones from scratch each time. |
| ChromosomePoolTest.java | Class | Tests the ChromosomePool class. |
| CompositeGene.java | Class | Ordered container for multiple genes
Has the same interface as a single gene and could be used accordingly.
Use the addGene(Gene) method to add single genes (possibly CompositeGenes)
after construction, an empty CompositeGene without genes makes no sense.
Beware that there are two equalities defined for a CompositeGene in respect
to its contained genes:
a) Two genes are (only) equal if they are identical
b) Two genes are (seen as) equal if their equals method returns true
This influences several methods such as addGene. |
| CompositeGenePersistentReprTest.java | Class | Test persistent representation of the CompositeGene. |
| CompositeGeneTest.java | Class | Tests the CompositeGene class. |
| CrossoverOperator.java | Class | The crossover operator randomly selects two Chromosomes from the

Chromosomes. |

| DoubleGeneTest.java | Class | Tests the DoubleGene class. |
| FittestPopulationMerger.java | Class | A implementation of the IPopulationMerger interface that merges two
populations as specified based on the fitness function, that is, the n
fittest chromosomes are returned in the new population, where n is supplied
by parameter. |
| FittestPopulationMergerTest.java | Class | Tests the FittestPopulationMerger class. |
| FixedBinaryGene.java | Class | A Gene implementation that supports two possible values (alleles, 1 and 0)
with a fixed length of alleles.
NOTE: Since this Gene implementation only supports two different
values (1 and 0), there's only a 50% chance that invocation
of the setToRandomValue() method will actually change the value of
this Gene (if it has a value). |
