TSP_IO is a FORTRAN90 library which is intended to be used to read or write some of the formats used in TSPLIB, a collection of traveling salesman problems stored in a particular format known as "TSP".
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
TSP_IO is available in a FORTRAN90 version.
CITIES, a dataset directory which contains sets of information about cities and the distances between them;
CITIES, a FORTRAN90 library which handles various problems associated with a set of "cities" on a map.
TSP, a dataset directory which contains test data for the traveling salesperson problem;
TSP_BRUTE, a FORTRAN90 program which reads a file of city-to-city distances and solves the traveling salesperson problem, using brute force.
TSP_LAU, a FORTRAN90 library which implements a heuristic algorithm for the solution of the traveling salesperson problem, by Hang Tong Lau.
P01 is a small example of 15 cities.
ATT48 is a classic example of 48 cities.
