Algorithm 3

GA_RF_FS .

Input: New training dataset , testing dataset

Output: Optimal feature subset

Generate initial population

While not reach terminating condition

Calculate fitness (, , )

Selection()

/, are probabilities of crossover and mutation respectively./

Crossover (, )

Mutation (, )

End While

= Chromosome with the highest fitness in

= Convert to feature number
