C# Class Accord.Genetic.PermutationChromosome

Permutation chromosome.

Permutation chromosome is based on short array chromosome, but has two features:

all genes are unique within chromosome, i.e. there are no two genes with the same value; maximum value of each gene is equal to chromosome length minus 1.

Inheritance: ShortArrayChromosome

Public Methods

Method	Description
Clone ( ) : IChromosome	Clone the chromosome. The method clones the chromosome returning the exact copy of it.
CreateNew ( ) : IChromosome	Create new random chromosome with same parameters (factory method). The method creates new chromosome of the same type, but randomly initialized. The method is useful as factory method for those classes, which work with chromosome's interface, but not with particular chromosome type.
Crossover ( IChromosome pair ) : void	Crossover operator. The method performs crossover between two chromosomes – interchanging some parts between these chromosomes.
Generate ( ) : void	Generate random chromosome value. Regenerates chromosome's value using random number generator.
Mutate ( ) : void	Mutation operator. The method performs chromosome's mutation, swapping two randomly chosen genes (array elements).
PermutationChromosome ( int length ) : Accord.Math.Random	Initializes a new instance of the PermutationChromosome class.

Protected Methods

Method	Description
PermutationChromosome ( PermutationChromosome source ) : Accord.Math.Random	Initializes a new instance of the PermutationChromosome class. This is a copy constructor, which creates the exact copy of specified chromosome.

Private Methods

Method	Description
CreateChildUsingCrossover ( ushort parent1, ushort parent2, ushort child ) : void
CreateIndexDictionary ( ushort genes ) : ushort[]

Method Details

Clone() public method

Clone the chromosome.

The method clones the chromosome returning the exact copy of it.

public Clone ( ) : IChromosome
return	IChromosome

CreateNew() public method

Create new random chromosome with same parameters (factory method).

The method creates new chromosome of the same type, but randomly initialized. The method is useful as factory method for those classes, which work with chromosome's interface, but not with particular chromosome type.

public CreateNew ( ) : IChromosome
return	IChromosome

Crossover() public method

Crossover operator.

The method performs crossover between two chromosomes – interchanging some parts between these chromosomes.

public Crossover ( IChromosome pair ) : void
pair	IChromosome	Pair chromosome to crossover with.
return	void

Generate() public method

Generate random chromosome value.

Regenerates chromosome's value using random number generator.

public Generate ( ) : void
return	void

Mutate() public method

Mutation operator.

The method performs chromosome's mutation, swapping two randomly chosen genes (array elements).

public Mutate ( ) : void
return	void

PermutationChromosome() protected method

Initializes a new instance of the PermutationChromosome class.

This is a copy constructor, which creates the exact copy of specified chromosome.
