R package TSP - Infrastructure for the Traveling Salesperson Problem

Introduction

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.

The following R packages use TSP: archetypes, cholera, colorpatch, condvis, CRTspat, ForagingOrg, isocir, jocre, MLCOPULA, nilde, nlnet, PairViz, pencopulaCond, SCORPIUS, sensitivity, seriation, sfnetworks, tspmeta, VineCopula, vines

Installation

Stable CRAN version: Install from within R with

install.packages("TSP")

Current development version: Install from r-universe.

install.packages("TSP",
    repos = c("https://mhahsler.r-universe.dev",
              "https://cloud.r-project.org/"))

Usage

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

library("TSP")
data("USCA312")

tsp <- TSP(USCA312)
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: 40959

Show the first few cities in the tour.

head(tour, n = 10)

##   Bakersfield, CA        Fresno, CA      Stockton, CA      Berkeley, CA 
##                17                99               268                26 
##       Oakland, CA San Francisco, CA      San Jose, CA    Santa Cruz, CA 
##               186               241               242               245 
##          Hilo, HI      Honolulu, HI 
##               119               120

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