java.lang.Object

org.licas.ai_solver.model.genetic.genes.EvolveGenes

org.licas.ai_solver.model.genetic.genes.DefaultEvolveGenes

public class DefaultEvolveGenes
extends EvolveGenes

This is the default implementation for combining two different gene lists through crossover or mutation to generate a new one. This will only evolve one gene value at a time

Constructor Detail

DefaultEvolveGenes

public DefaultEvolveGenes(java.lang.String thisGeneType,
                          java.util.ArrayList<java.lang.String> thisEvolveTypes)

Create a new instance of DefaultEvolveGenes.

Parameters:

thisGeneType - the type of gene as the object classname.

thisEvolveTypes - the different ways that a crossover or mutation can be performed.

Method Detail

areSame

public boolean areSame(java.util.ArrayList<?> geneList1,
                       java.util.ArrayList<?> geneList2)
                throws java.lang.Exception

Return true if the two sets of genes are the same.

Specified by:

areSame in class EvolveGenes

Parameters:

geneList1 - the first list of consider.

geneList2 - the second list to consider.

Returns:

true if the genes are the same. This implementation returns false by default. You need to override this implementation to make any real comparison.

Throws:

java.lang.Exception - any error.

crossover

protected java.util.ArrayList<?> crossover(java.util.ArrayList<?> geneList1,
                                           java.util.ArrayList<?> geneList2)
                                    throws java.lang.Exception

Generate a crossover between this gene list and the variable passed in. This version randomly selects a gene from list 2 and swaps a gene from list 1 in the same position with it.

Specified by:

crossover in class EvolveGenes

Parameters:

geneList1 - the first list of consider.

geneList2 - the second list to consider.

Returns:

the result of the crossover. Can return null.

Throws:

java.lang.Exception - any error.

mutate

protected java.util.ArrayList<?> mutate(java.util.ArrayList<?> geneList1,
                                        java.util.ArrayList<?> geneList2)
                                 throws java.lang.Exception

Generate a mutation between this gene list and the variable passed in. This version randomly selects a gene from list 1 and list 2. It adds them together, removes the selected gene from list 1 and replaces it with the mutated gene. This uses the default evaluation service to add the gene values together.

Specified by:

mutate in class EvolveGenes

Parameters:

geneList1 - the first list of consider.

geneList2 - the second list to consider.

Returns:

the result of the mutation. Can return null.

Throws:

java.lang.Exception - any error.
