TSP (version 0.1-2)

TSP: Class TSP -- Symmetric traveling salesperson problem

Description

Constructor to create an instance of a symmetric traveling salesperson problem (TSP) and some auxiliary methods.

Usage

## constructor
TSP(x)
## methods
## S3 method for class 'TSP':
n_of_cities(x)
## S3 method for class 'TSP':
image(x, order, col = gray.colors(64), ...)
## S3 method for class 'TSP':
labels(object, \ldots)
## S3 method for class 'TSP':
print(x, \ldots)

Arguments

x, object

an object (currently dist or a symmetric matrix) to be converted into a TSP or, for the methods, an object of class TSP.

col

color scheme for image.

order

order of cities for the image as an integer vector or an object of class TOUR.

...

further arguments are passed on.

Value

• TSP() returns x as an object of class TSP.

  n_of_cities() returns an the number of cities in x.

  labels() returns a vector of the names of the cities in x.

Details

Objects of class TSP are internally represented as dist objects.
