Constructor Detail

CromDNF

public CromDNF(int length,
               TableVar Variables)

Creates new instance of chromosome, no initialization

Parameters:

length - Length of the chromosome

Variables - Variables table.

Method Detail

initCromRnd

public void initCromRnd()

Random initialization of an existing chromosome

initCromBsd

public void initCromBsd(float porcVar)

Biased Random initialization of an existing chromosome The random inicializacion is biased by generating chromosomes with a maximum number or participating variables and for an indicated % of the population (the rest is random)

Parameters:

porcVar - percentage of variables to appear in the biased initialization

getCromElemGene

public int getCromElemGene(int pos,
                           int elem)

Retuns the value of the gene indicated

Parameters:

pos - Position of the variable in the chromosome

elem - Position of the gene of the variable

Returns:

Value of the gene

setCromElemGene

public void setCromElemGene(int pos,
                            int elem,
                            int value)

Sets the value of the indicated gene of the chromosome

Parameters:

pos - Position of the variable in the chromosome

elem - Position of the gene of the variable

value - Value of the gene

getCromLength

public int getCromLength()

Retuns the length of the chromosome

Returns:

Length of the chromosome

getCromGeneLength

public int getCromGeneLength(int pos)

Retuns the gene lenght of the chromosome

Parameters:

pos - gene's position.

Returns:

the gene lenght of the chromosome

print

public void print(java.lang.String nFile)

Prints the chromosome genes

Parameters:

nFile - Files to write the chromosome

print

public java.lang.String print()

Gets the chromosome genes

Returns:

The chromosome in a string
