3.3. Normalization
The results of the calculation of fitness values are obtained from the results of normalization. Normalization data is a form of data transformation to group different ranges of values into the same value scale 14. There are several normalization methods that can be used, but in this case study we use the min – max normalization method. Min – max Normalization is a linear transformation process in the original data 15. Equation 2 is the formula of min – max normalization.
