Algorithm 4
Algorithm 4: Deletion operator.
Output: P (updated population) | (1) | while | P | > N | (2) | normalize P | (3) | compute HAD values of solutions in P by equation (5) | (4) | find the most crowded subregion by equation (6) | (5) | divide all solutions in into S1, …, SK by equation (7) | (6) | find the most crowded cluster Sk by equation (8) | (7) | find x with the smallest HAD value in Sk | (8) | delete x from and P | (9) | end while | (10) | return P |
