 2opt is an approximate algorithm and does not give the optimal solution every time. 
 
 For example: when run on a280.tsp if the algorithm starts from the first node (index 0) then it's solution is 2756.788 units long. Whereas if it starts from the second node (index 1) then it's solution is 2727.229 units long.
