tour_length

From TSP v1.1-4 by Michael Hahsler

Calculate the length of a tour

Calculate the length of a tour given a TSP and an order.

Keywords: optimize

Usage

tour_length(x, ...)
"tour_length"(x, tsp = NULL, ...)

Arguments

x: an object of class TOUR.
tsp: a TSP object of class TSP, ATSP or ETSP.
...: further arguments are currently unused.

Details

If no tsp is given, then the tour length stored in x as attribute "tour_length" is returned. If tsp is given then the tour length is recalculated. If a distance in the tour is infinite, the result is also infinite. If the tour contains positive and negative infinite distances then the method returns NA.

Examples

data("USCA50")

## original order
tour_length(solve_TSP(USCA50, method="identity"))

## length of a manually created (random) tour
tour <- TOUR(sample(seq(n_of_cities(USCA50))))
tour
tour_length(tour)
tour_length(tour, USCA50)
