Constructor Detail

DoubleChromosome

protected DoubleChromosome(ISeq<DoubleGene> genes)

DoubleChromosome

public DoubleChromosome(Double min,
                        Double max,
                        int length)

Create a new random DoubleChromosome.

Parameters:

min - the min value of the DoubleGenes (inclusively).

max - the max value of the DoubleGenes (exclusively).

length - the length of the chromosome.

Throws:

NullPointerException - if one of the arguments is null.

DoubleChromosome

public DoubleChromosome(Double min,
                        Double max)

Create a new random DoubleChromosome of length one.

Parameters:

min - the minimal value of this chromosome (inclusively).

max - the maximal value of this chromosome (exclusively).

Throws:

NullPointerException - if one of the arguments is null.

Method Detail

toArray

public double[] toArray(double[] array)

Returns an double array containing all of the elements in this chromosome in proper sequence. If the chromosome fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the length of this chromosome.

Parameters:

array - the array into which the elements of this chromosomes are to be stored, if it is big enough; otherwise, a new array is allocated for this purpose.

Returns:

an array containing the elements of this chromosome

Throws:

NullPointerException - if the given array is null

Since:

3.0

toArray

public double[] toArray()

Returns an double array containing all of the elements in this chromosome in proper sequence.

Returns:

an array containing the elements of this chromosome

Since:

3.0

of

public static DoubleChromosome of(DoubleGene... genes)

Create a new DoubleChromosome with the given genes.

Parameters:

genes - the genes of the chromosome.

Returns:

a new chromosome with the given genes.

Throws:

IllegalArgumentException - if the length of the genes array is empty.

of

public static DoubleChromosome of(double min,
                                  double max,
                                  int length)

Create a new random DoubleChromosome.

Parameters:

min - the min value of the DoubleGenes (inclusively).

max - the max value of the DoubleGenes (exclusively).

length - the length of the chromosome.

Returns:

a new DoubleChromosome with the given parameter

of

public static DoubleChromosome of(double min,
                                  double max)

Create a new random DoubleChromosome of length one.

Parameters:

min - the minimal value of this chromosome (inclusively).

max - the maximal value of this chromosome (exclusively).

Returns:

a new DoubleChromosome with the given parameter

newInstance

Specified by:

newInstance in interface Factory<Chromosome<DoubleGene>>

Returns:

a new instance of type T

hashCode
