之前研究布谷鸟算法，一直在找levy飞行轨迹代码实现，一直没找到就自己写了一个
x = [0,0];
y = [0,0];
beta = 3/2;
alpha_u = ((gamma(1+beta)*sin(pi*beta/2)/(gamma((1+beta)/2)*beta*2^((beta-1)/2))))^(1/beta);
alpha_v = 1;
for i=1:1000
u = alpha_u*randn(1);
v = alpha_v*randn(1);
s = u/(abs(v))^(1/beta);
x(:,1) = x(:,2);
x(:,2) = x(:,1)+1*s;
u = alpha_u*randn(1);
v = alpha_v*randn(1);
s = u/(abs(v))^(1/beta);
y(:,1) = y(:,2);
y(:,2) = y(:,1)+1*s;
plot(x,y);
hold on;
end
axis square;
迭代1000次运行结果：
