Webproblem becomes usual TSP. The distance matrix may represent cost, time, etc. Depending on the nature of the distance matrix, the TSPs are divided into two types - asymmetric and symmetric. If d ij = d ji, i, j, then it is symmetric; otherwise, asymmetric. For n-city usual asymmetric TSP, there are (n-1)! possible number of routes.
