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 `BinaryChromosome`s.
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 `RandomKey`s.
TournamentSelection | Tournament selection scheme.
UniformCrossover<T> | Perform Uniform Crossover [UX] on the specified chromosomes.

Exception Summary

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