DataBase

public DataBase()

Default constructor

DataBase

public DataBase(int partitions,
                int n_variables,

                java.lang.String[] names)

Constructor with parameters. It performs a homegeneous partition of the input space for a each number of partitions

Parameters:

partitions - int Number of fuzzy partitions

n_variables - int Number of input variables of the problem

ranges - double[][] ranges of each variable (minimum and maximum values)

names - String[] Labels for the input attributes
