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.

I'm sure that a lot of times, because the continued use of this phrase, have been converted in the regular way of talking of all the people and is totally incorrect. Something seemed happens when say that we weight 154 pounds, being the pound a unit of mass and not of weight. We must say: "I weight 70 kiloponds" or "I weight 154 pounds-force". Follow reading if you want to know why the case of the megs of bandwidth, also is incorrect. Show more of "The Megs of bandwidth doesn't exists"
