Constructor Detail

BitChain

public BitChain(int[] pChain)

Creates a new instance of BitChain from an array of integers.

Parameters:

pChain - chain of bits that represents the individual.

BitChain

public BitChain(int pSize)

Creates a new instance (full of 0s) with the specified size.

BitChain

public BitChain(BitChain oldBitChain)

Create a new instance of BitChain from another object

Parameters:

oldBitChain - object from which values are taken

Method Detail

getCopyOfElements

public int[] getCopyOfElements()

Returns a copy of the elements which form the individual.

Returns:

A vector containing the elements of the individual.

getElements

public int[] getElements()

Returns a reference to the elements which form the individual.

Returns:

A vector containing the elements of the individual.

setElements

public void setElements(int[] elements)

Sets the elements of a individual from an array of integer.

Parameters:

elements - Array of integers that code the individual.

get

public int get(int pos)

Returns the value stored in position pos.

Parameters:

pos - Position whose value is required.

Returns:

Value in the position pos.

set

public void set(int pos,
                int value)

Fixes element value in this position.

Parameters:

pos - Position whose value must be changed.

value - for this position.

toString

public java.lang.String toString()

String representation of the individual.

Specified by:

toString in class Individual

Returns:

A string representing the individual.

clone

public java.lang.Object clone()

Description copied from class: Individual

Clones an individual. It allows to copy individuals instead of references.

Specified by:

clone in class Individual

Returns:

an object similar to this.

intToIndividual

public static BitChain[] intToIndividual(int[][] pSample)

Static method which allows building an array of individuals from a matrix of integer.

Parameters:

pSample - Two dimension matrix containing the values for the individuals.

Returns:

An array of BitChain each one of them built from one of the arrays.
