Class BooleanChromosome

java.lang.Object

jenes.chromosome.BooleanChromosome

All Implemented Interfaces:

java.lang.Cloneable, Chromosome<BooleanChromosome>

public final class BooleanChromosome
extends java.lang.Object
implements Chromosome<BooleanChromosome>

A BooleanChromosome is made of an array of booleans. Each gene can assume the value true or false. A faster and less memory demanding alternative to BooleanChromosome is provided by BitwiseChromosome with BooleanCoding.

Constructor Detail

BooleanChromosome

public BooleanChromosome(BooleanChromosome chromosome)

Creates a new BooleanChromosome with the specified chromosome

Parameters:

chromosome - the parameters source chromosome

BooleanChromosome

public BooleanChromosome(int size)

Creates a new BooleanChromosome with the specified chromosome length

Parameters:

size - the chromosome length

Method Detail

setDefaultValueAt

public final void setDefaultValueAt(int pos)

Description copied from interface: Chromosome

Sets the default value at a given position

Specified by:

setDefaultValueAt in interface Chromosome<BooleanChromosome>

Parameters:

pos - the position where to set the default value

clone

public final BooleanChromosome clone()

Description copied from interface: Chromosome

Performs a chromosome deep-cloning.

Specified by:

clone in interface Chromosome<BooleanChromosome>

Overrides:

clone in class java.lang.Object

Returns:

a chromosome clone.

randomize

public final void randomize()

Description copied from interface: Chromosome

Fills the chromosome with random value.

Specified by:

randomize in interface Chromosome<BooleanChromosome>

randomize

public final void randomize(int pos)

Description copied from interface: Chromosome

Sets a random value in the specified position

Specified by:

randomize in interface Chromosome<BooleanChromosome>

Parameters:

pos - a position where to set the random value

swap

public final void swap(int pos1,
        int pos2)

Description copied from interface: Chromosome

Exchanges two genes at the specified positions

Specified by:

swap in interface Chromosome<BooleanChromosome>

Parameters:

pos1 - the position of first gene

pos2 - the position of second gene

leftShift

public final void leftShift(int from,
             int to)

Description copied from interface: Chromosome

Makes a left-shift of the genes between two positions. The shift is circular, so the most left-side gene becomes the last gene on right.

Specified by:

leftShift in interface Chromosome<BooleanChromosome>

Parameters:

from - the start position to be shifted

to - the final position to be shifted

rightShift

public final void rightShift(int from,
              int to)

Description copied from interface: Chromosome

Makes a right-shift of the genes between two positions. The shift is circular, so the most right-side gene becomes the first gene on left.

Specified by:

rightShift in interface Chromosome<BooleanChromosome>

Parameters:

from - the start position to be shifted

to - the final position to be shifted

length

public final int length()

Description copied from interface: Chromosome

Returns the number of genes contained in the chromosome.

Specified by:

length in interface Chromosome<BooleanChromosome>

Returns:

the length of chromosome.

setAs

public final void setAs(BooleanChromosome chromosome)

Description copied from interface: Chromosome

Makes the chromosome a copy of another chromosome.

Specified by:

setAs in interface Chromosome<BooleanChromosome>

Parameters:

chromosome - the chromosome to be copied

cross

public final void cross(BooleanChromosome chromosome,
         int from)

Description copied from interface: Chromosome

Exchanges the genes chromosome starting from a given position

Specified by:

cross in interface Chromosome<BooleanChromosome>

Parameters:

chromosome - the chromosome to cross with

from - the start position of the genes to exchange

cross

public final void cross(BooleanChromosome chromosome,
         int from,
         int to)

Description copied from interface: Chromosome
