| TSP {TSP} | R Documentation |
Constructor to create an instance of a symmetric traveling salesperson problem (TSP) and some auxiliary methods.
## constructor TSP(x, labels = NULL) ## coercion as.TSP(object) ## 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, ...) ## S3 method for class 'TSP': print(x, ...)
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. |
labels |
optional city labels. If not given, labels are taken
from x. |
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. |
Objects of class TSP are internally represented as dist objects
(use as.dist() to get the dist object).
TSP() returns x as an object of class TSP.
n_of_cities() returns the number of cities in x.
labels() returns a vector with the names of the cities in x.
TOUR,
insert_dummy,
tour_length,
solve_TSP.
