help optimization Simulated Annealing
显示 更早的评论
Hey, i have this programme but he didn t work somone know why ?
function T=f(xe,ye)
T=sin(xe)*sin(ye)+0.1*xe;
end
function w=g(xn,yn)
w=sin(xn)*sin(yn)+0.1*xn;
end
for xe= -4:4
for ye= -4:4
while (T>Tfinale && nb_iter< 5000)
xn=xe+ampli*rand;
yn=ye+ampli*rand;
if g(xn,yn) < f(xe,ye)
xe=xn;
ye=yn;
else
df= g(xn,yn)-f(xe,ye);
p=exp(-df/T);
if(p>rand)
xe=xn;
ye=yn;
end
end
T=lamda*T;
nb_iter = nb_iter+1;
end
end
end

When you put a script and functions in the same file, the script must be the first thing in the file.
You do not initialize T or Tfinale or nb_iter or lamda
You appear to be accepting at random, as is done for simulated annealing, but you do not appear to be keeping track of the best position that was ever encountered.

And of course (my pet peeve) there are no comments describing what the code is doing. That leads to unmaintainable code.
