Google is your friend. 1st site.

The traveling salesman problem, or TSP for short, is this: given a finite number of "cities" along with the cost of travel between each pair of them, find the cheapest way of visiting all the cities and returning to your starting point. In these pages we report on our ongoing project to solve large-scale instances of the TSP.

The "problem" is that there is (as yet) no formula for solving this problem - you have to test all possible combinations. There are mathematical techniques for dealing with this problem, but the "problem" for the maths heads is that no solution that they can produce is *_proveably_* correct.
