(5)The position of the bald eagle is updated by equation (4);
(6)
(7)The position of the bald eagle is updated by equation (6);
(8)
(9)The position of the bald eagle is updated by equation (8);
(10)
(11)The new current position is obtained;
(12)The position is updated when the new position is better than the previous one;
