Package org.apache.commons.math4.legacy.genetics

This package provides Genetic Algorithms components and implementations.

Interface Summary

Interface	Description
CrossoverPolicy	Policy used to create a pair of new chromosomes by performing a crossover operation on a source pair of chromosomes.
Fitness	Fitness of a chromosome.
MutationPolicy	Algorithm used to mutate a chromosome.
PermutationChromosome<T>	Interface indicating that the chromosome represents a permutation of objects.
Population	A collection of chromosomes that facilitates generational evolution.
SelectionPolicy	Algorithm used to select a chromosome pair from a population.
StoppingCondition	Algorithm used to determine when to stop evolution.

Class Summary

Class	Description
AbstractListChromosome<T>	Chromosome represented by an immutable list of a fixed length.
BinaryChromosome	Chromosome represented by a vector of 0s and 1s.
BinaryMutation	Mutation for BinaryChromosomes.
Chromosome	Individual in a population.
ChromosomePair	A pair of Chromosome objects.
CycleCrossover<T>	Cycle Crossover [CX] builds offspring from ordered chromosomes by identifying cycles between two parent chromosomes.
ElitisticListPopulation	Population of chromosomes which uses elitism (certain percentage of the best chromosomes is directly copied to the next generation).
FixedElapsedTime	Stops after a fixed amount of time has elapsed.
FixedGenerationCount	Stops after a fixed number of generations.
GeneticAlgorithm	Implementation of a genetic algorithm.
ListPopulation	Population of chromosomes represented by a List.
NPointCrossover<T>	N-point crossover policy.
OnePointCrossover<T>	One point crossover policy.
OrderedCrossover<T>	Order 1 Crossover [OX1] builds offspring from ordered chromosomes by copying a consecutive slice from one parent, and filling up the remaining genes from the other parent as they appear.
RandomKey<T>	Random Key chromosome is used for permutation representation.
RandomKeyMutation	Mutation operator for RandomKeys.
TournamentSelection	Tournament selection scheme.
UniformCrossover<T>	Perform Uniform Crossover [UX] on the specified chromosomes.

Exception Summary

Exception	Description
InvalidRepresentationException	Exception indicating that the representation of a chromosome is not valid.
