Package	Description
io.jenetics	This is the base package of the Jenetics library and contains all domain classes, like Gene, Chromosome or Genotype.
io.jenetics.stat	This package contains additional statistics classes which are not available in the Java core library.
io.jenetics.util	This package contains the collection classes (Seq, ISeq and MSeq) which are used in the public interfaces of the Chromosome and Genotype.

Class	Description
Codec<T,G extends Gene<?,G>>	A problem Codec contains the information about how to encode a given argument type into a Genotype.
Codecs	This class contains factory methods for creating common problem encodings.
Constraint<G extends Gene<?,G>,C extends Comparable<? super C>>	This interface allows you to define constraints on single phenotypes.
Engine<G extends Gene<?,G>,C extends Comparable<? super C>>	Genetic algorithm engine which is the main class.
Engine.Builder<G extends Gene<?,G>,C extends Comparable<? super C>>	Builder class for building GA Engine instances.
Engine.Setup<G extends Gene<?,G>,C extends Comparable<? super C>>	This interface represents a recipe for configuring (setup) a given Engine.Builder.
Evaluator<G extends Gene<?,G>,C extends Comparable<? super C>>	This interface allows defining different strategies for evaluating the fitness functions of a given population.
Evaluators	This class contains factory methods for creating commonly usable Evaluator implementations.
Evolution<G extends Gene<?,G>,C extends Comparable<? super C>>	This functional interface defines the evolution function, which takes an EvolutionStart object, evolves the population, and returns an EvolutionResult object.
EvolutionDurations	This class contains timing information about one evolution step.
EvolutionInit<G extends Gene<?,G>>	Represents the initialization value of an evolution stream/iterator.
EvolutionInterceptor<G extends Gene<?,G>,C extends Comparable<? super C>>	The evolution interceptor allows updating the EvolutionStart object, before the evolution start, and update the EvolutionResult object after the evolution.
EvolutionParams<G extends Gene<?,G>,C extends Comparable<? super C>>	This class collects the parameters which control the behavior of the evolution process.
EvolutionParams.Builder<G extends Gene<?,G>,C extends Comparable<? super C>>	Builder class for the evolution parameter.
EvolutionResult<G extends Gene<?,G>,C extends Comparable<? super C>>	Represents a state of the GA after an evolution step.
EvolutionStart<G extends Gene<?,G>,C extends Comparable<? super C>>	Represents a state of the GA at the start of an evolution step.
EvolutionStatistics<C extends Comparable<? super C>,FitnessStatistics>	This class can be used to gather additional statistic information of an evolution process.
EvolutionStream<G extends Gene<?,G>,C extends Comparable<? super C>>	The EvolutionStream class extends the Java Stream and adds a method for limiting the evolution by a given predicate.
EvolutionStreamable<G extends Gene<?,G>,C extends Comparable<? super C>>	This interface defines the capability of creating EvolutionStreams from a given EvolutionStart object.
FitnessNullifier<G extends Gene<?,G>,C extends Comparable<? super C>>	This class allows forcing a reevaluation of the fitness function.
InvertibleCodec<T,G extends Gene<?,G>>	This interface extends the Codec and allows to encode an object from the problem space to a corresponding Genotype, which is the inverse functionality of the codec.
Limits	This class contains factory methods for creating predicates, which can be used for limiting the evolution stream.
Problem<T,G extends Gene<?,G>,C extends Comparable<? super C>>	This interface describes a problem which can be solved by the GA evolution Engine.
RetryConstraint<G extends Gene<?,G>,C extends Comparable<? super C>>	This simple Constraint implementation repairs an invalid phenotype by creating new individuals until a valid one has been created.
