Table 1

List of the parameters of the HFC-PSSA and boundaries of search space.

HFC-PSSA parameters
Number of generations	200
Number of subpopulations	6
Number of subsolutions	[40,40,40,40,40,40]
Migration interval	25 generations
Number of solutions for search space; (Case I)	8
Boundary of search space of decision variables
Fuzzification coefficient	1.01~5
Number of input variables∗	2~10
Number of rules	2~20
Order of polynomials of each fuzzy rule	1~4 (type 1~type 4)

∗If the number of input variables in dataset is smaller than 10, then we use the number of all input variables.
