How to find the lowest value of Dist?

x=[1 2 3 4 5];

d= [0 10 20 30 40;
    10 0 50 60 70;
    20 50 0 80 90;
    30 60 80 0 100;
    40 70 90 100 0]; 

n=2;
for k=1:n
xp = randperm(numel(x), 2);
x(xp) = x(fliplr(xp))
s = sub2ind(size(d),x(1:end-1),x(2:end ));
Dist = sum(d(s)) 
end

for k=1:n
xp = randperm(numel(x), 4);
x(xp) = x(fliplr(xp))
s = sub2ind(size(d),x(1:end-1),x(2:end ));
Dist = sum(d(s)) 
end

lowest_Dist = ?

Index Dist:

Dist(k) = sum(d(s))

Then, perhaps:

lowest_Dist = min(Dist)

If not, why not?

Did this work for you, or not??
