TOUR
(Package: TSP) :
Class TOUR -- Solution to a traveling salesperson problem
Class to store the solution of a TSP. Objects of this class are returned by TSP solvers in this package. Essentially, an object of class TOUR is a permutation vector containing the order of cities to visit.
Concorde
(Package: TSP) :
Using the Concorde TSP Solver
The Concorde TSP Solver package contains several solvers. Currently, interfaces to the Concorde solver (Applegate et al. 2001), one of the most advanced and fastest TSP solvers using branch-and-cut, and the Chained Lin-Kernighan (Applegate et al. 2003) implementation are provided in TSP.
insert_dummy
(Package: TSP) :
Insert dummy cities into a distance matrix
Inserts dummy cities into objects of class TSP or ATSP. A dummy city has the same, constant distance (0) to all other cities and is infinitely far from other dummy cities. A dummy city can be used to transform a shortest Hamiltonian path problem (i.e., finding an optimal linear order) into a shortest Hamiltonian cycle problem which can be solved by a TSP solvers (Garfinkel 1985).
TSPLIB
(Package: TSP) :
Read and write TSPLIB files
Reads and writes TSPLIB format files. TSPLIB files can be used by most TSP solvers. Sample instances for the TSP in TSPLIB format are available on the TSPLIB homepage (see references).
