plot_tour {gor}

TSP tour simple plotting

Description

Plotting tours constructed by tour-building routines for TSP

Usage

plot_tour(z, h, ...)

Arguments

z

Set of points of a TSP

h

List with $tour and $distance components returned from a TSP tour building algorithm

...

Parameters to be passed to plot

Details

It plots the two-dimensional cities of a TSP and a tour among them for visualization purposes. No aesthetically appealing effort has been invested in this function.

Value

This function is called by its side effect.
