TSP - Traveling Salesperson Problem - R package

CRAN version CRAN RStudio mirror downloads Travis-CI Build Status AppVeyor Build Status

This package provides the basic infrastructure and some algorithms for the traveling salesman problems (symmetric, asymmetric and Euclidean TSPs). The package provides some simple algorithms and an interface to the Concorde TSP solver and its implementation of the Chained-Lin-Kernighan heuristic.

Installation

Stable CRAN version: install from within R with

install.packages("TSP")

Current development version: Download package from AppVeyor or install from GitHub (needs devtools).

install_git("mhahsler/TSP")

Usage

Load a data set with 312 cities (USA and Canada) and create a TSP object.

R> library("TSP")
R> data("USCA312")

R> tsp <- TSP(USCA312)
R> tsp
object of class 'TSP'
312 cities (distance   'euclidean')

Find a tour using the default heuristic.

tour <- solve_TSP(tsp)
tour
object of class 'TOUR' 
result of method 'arbitrary_insertion+two_opt' for 312 cities
tour length: 40621

An online example application of TSP can be found on shinyapps.
