initiation.m

介绍了粒子群模拟退火算法在函数优化中的应用

%该函数初始化粒子，同时计算出粒子的局部最佳值和全局最佳值以及适应值
function [pop,gbest,zbest,fitnessgbest,fitnesszbest,V] = initiation(n,m)
pop = rands(n,m)*10;
gbest = pop;
fitness = caculate(pop,n,m);
fitnessgbest = fitness;
V = rands(n,m)*3;
fitnesszbest = fitness(1);
k = 1;
for i = 2:n
    if fitness(i) < fitnesszbest
        k = i;
        fitnesszbest = fitness(i);
    end
end
zbest = pop(k,:);
V = rands(n,m)*3;
