Algorithm 2

Algorithm 2: Addition operator.

Output: P (updated population)
(1)	set P to be an empty set
(2)	P = P ∪ F1
(3)	for k = 1 to K
(4)	(f1, …, ft) = Non-dominated Sorting (Ck)
(5)	P = P  ∪ f1
(6)	end for
(7)	i = 1
(8)	while |P| < N
(9)	i = i + 1
(10)	P = P ∪ Fi
(11)	end while
(12)	return P
