endx.m

用matlab语言编的多维粒子群代吗

function ENDX(j,npop)
global Swarm
X = [Swarm(j).individual.number];
m = 5; 
nc = 20;
alpha = 0.434;
beta = 0.35 / sqrt(m-3) ;
index = randperm(npop);
p = X(index(1:m));
for i = 1 : nc
    c(i) = (p(1) + p(2)) / 2 + alpha^2 * randn * (p(2) - p(1)) + sum((beta^2 * randn(1, m-2)).*(p(3:m) - sum(p(3:m)) / (m-2)));
end
X = [X c];
i = round(rand*(size(X,1)-1)+1);
Swarm(j).individual(index(2)).number = X(i);
Swarm(j).individual(index(1)).number = Swarm(j).P;
