it is an 5 cities tsp problem.

DIST = [ 0 2 5 8 3

.............

............

7 6 3 4 0] it is a 5 x 5 matrix

path =[ 1 2 3 4 5

1 2 3 5 4

Can you give an explicit example of your desired output?

take 1st row of path [1 2 3 4 5] it means 1st row and 2nd column of th DIST value it takes (2) then 2nd row and 3rd column of the DIST likewise do it for all and store the values in one matrix
