numReglas - number of rules

Method Detail

getGene

public double getGene(int pos)

It returns the value of the gene at position i

Parameters:

pos - the specific position

Returns:

the value of that gene

setGene

public void setGene(int pos,
                    double valor)

Sets a value for a specific gene

Parameters:

pos - the gene position inside the chromosome

valor - the new value

setExitos

public void setExitos(int pos,
                      int valor)

Sets the number of correctly classified instances for a rule of the chromosome

Parameters:

pos - rule id

valor - new value

setFracasos

public void setFracasos(int pos,
                        int valor)
