The matrix dist is used to store the distance between each point, that is, (dist)ij is the distance between points I and J.

N = size(dist， 1)；

seq = 1: 1:N；

perm = perms(seq)；

size_perm = size(perm， 1)；

min _ dist = inf

for i = 1: 1:size_perm

total _ dist = 0；

For j = 1: 1:N

total_dist = total_dist + dist(j，perm(i，j))；

end

If total _ dist & lt minimum distance

min _ dist = total _ dist

end

end
