- an array containing the elements of this chromosome
- Throws:
NullPointerException
- if the givenarray
isnull
- 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

doesn't have the same range.NullPointerException
- if the givengenes
array isnull
-
of
public static DoubleChromosome of(Iterable<DoubleGene> genes)
Create a newDoubleChromosome
with the given genes.- Parameters:

NullPointerException
- if the givengenes
arenull
IllegalArgumentException
- if the of the genes iterable is empty or the givengenes
doesn't have the same range.- Since:
- 4.3
-
of
public static DoubleChromosome of(double min, double max, IntRange lengthRange)
Create a new random chromosome.- Parameters:

- the allowed length range of the chromosome.- Returns:
- a new
DoubleChromosome
with the given parameter - Throws:
IllegalArgumentException
- if the length of the gene sequence is empty, doesn't match with the allowed length range, the minimum or maximum of the range is smaller or equal zero or the given range size is zero.NullPointerException
- if the givenlengthRange
isnull
- Since:
- 4.0
-
of
public static DoubleChromosome of(double min, double max, int length)
Create a new randomDoubleChromosome

s (exclusively).length
- the length of the chromosome.- Returns:
- a new
DoubleChromosome
with the given parameter - Throws:
IllegalArgumentException
- if thelength
is smaller than one.
