   +----evolution.GeneticFactoryImpl
public abstract class GeneticFactoryImpl
extends Object
implements GeneticFactory
Default partial implementation of GeneticFactory. To be precise, I implement all methods that may be implemented without making assumptions on the concrete evolution type.

Variable Index

o rg

Constructor Index

o GeneticFactoryImpl()
Create myself with the default RandomGenerator seeded with a random seed.
o GeneticFactoryImpl(byte[])
Create myself with the default RandomGenerator seeded with the specified seed.
o GeneticFactoryImpl(RandomGenerator)
Create myself with the given random generator.
o GeneticFactoryImpl(RandomGenerator, byte[])
Create myself with the given random generator and seed.

Method Index

o getEvaluator()
o getNumParents()
Return the number of individuals that need to copulate for the creation of a child.
o getRandomGenerator()
o getSortingAlgorithm()
o merge(Genome[], EvolutionParm)
Merge the parent genomes to produce a child genome.
o newEmptyGenome()
o newIndividual()
Create a new individual.
o offspring(Individual[], EvolutionParm)
Produce a child from the parents' genomes.

Variables

o rg 
 protected RandomGenerator rg

Constructors

o GeneticFactoryImpl 
 public GeneticFactoryImpl(RandomGenerator r,
                           byte randomSeed[])
Create myself with the given random generator and seed.

o GeneticFactoryImpl 
 public GeneticFactoryImpl(RandomGenerator r)
Create myself with the given random generator.

o GeneticFactoryImpl 
 public GeneticFactoryImpl(byte seed[])
Create myself with the default RandomGenerator seeded with the specified seed.

o GeneticFactoryImpl 
 public GeneticFactoryImpl()
Create myself with the default RandomGenerator seeded with a random seed.

Methods

o newIndividual 
 public abstract Individual newIndividual() throws EvolutionException
Create a new individual.

Returns:
a new (random) Individual
o getNumParents 
 public abstract int getNumParents()
Return the number of individuals that need to copulate for the creation of a child. 1 is allowed, which amounts to a non-sexual evolution where the only genetic "input" is mutation.

Returns:
a natural number greater or equal to 1.
o getEvaluator 
 public abstract Evaluator getEvaluator()
Returns:
the Evaluator object used for this evolution.
o newEmptyGenome 
 protected abstract Genome newEmptyGenome()
Returns:
an empty new Genome
o offspring 
 public Individual offspring(Individual parents[],
                             EvolutionParm p) throws EvolutionException
Produce a child from the parents' genomes.

Throws: EvolutionException
if something goes wrong :-)
Throws: BadSizeException
if the number of prents is wrong
o getSortingAlgorithm 
 public SortingAlgorithm getSortingAlgorithm()
Returns:
the default SortingAlgorithm, viz. SortingAlgorithmImpl of JGL.
o merge 
 protected Genome merge(Genome parent[],
                        EvolutionParm parm) throws EvolutionException
Merge the parent genomes to produce a child genome.

Parameters:
parent - the parent genomes
Returns:
the new genome
o getRandomGenerator 
 public RandomGenerator getRandomGenerator()
Returns:
the RandomGenerator object used for this evolution.
