The travelling salesman is a problem computationally expensive to calculate. Its complexity is exponential and, therefore, is in the category of the problems that can't be solved in a polynomial time, in other words, it's as say that an actual computer can take a lot of millennia in get the solution to the problem. If we can get the result in less time will be useful to salesmen, transport agencies, postmen, distributors, infinity of fabrication process, DNA analysis and a lot of more situations.
