Travel salesman problem.
The Travelling Salesman problem is NP-hard, which means that it is very difficult to be solved by computers (at least for large numbers of cities). Finding a fast and exact algorithm would have serious implications in the field of computer science: it would mean that there are fast algorithms for all NP-hard problems.

This tutorial describes how to implement the Traveling Salesperson Problem in JuMP using solver-independent lazy constraints that dynamically separate subtours. To be more precise, we use lazy constraints to cut off infeasible subtours only when necessary and not before needed. First we have to solve those and substitute here. Here T ( 4, {} ) is reaching base condition in recursion, which returns 0 (zero ) distance. = { (1,2) + T (2, {3,4} ) 4+ 6 =10 in this path we have to add +1 because this path ends with 3.
