Input: Qi, BWi,j, , fi,j, B, t, epoch, i, j ∈ R
Output: Gbest
(1)	Set count, Gk, c1,c2, , , epoch, seed, X, V
(2)	for l = 1 to seed do
(3)	initialize velocity and position xi,j for particle
(4)	evaluate particle Xl and set pbestl = Xl
(5)	end for
(6)	for k = 1 to Gk do
(7)	update by (10);
(8)	for i = 1 to seed + s do
(9)	for j = 1 to h do
(10)	update X and V by (10)
(11)	Constrain the particle boundary
(12)	end for end for
(13)	if fit(Xi^k) < fit(pbesti) then
(14)	pbesti = Xi^k
(15)	if fit(Xi^k) < fit(Gbest) then
(16)	Gbest = Xi^k
(17)	end for
(18)	immune operation through formulas (14)–(16)
