makeNetwork: Generate network based on coordinates.

In jakobbossek/salesperson: Computation of Instance Features and R Interface to the State-of-the-Art Exact and Inexact Solvers for the Traveling Salesperson Problem

Description

Create a (clustered) network object.

Usage

makeNetwork(coordinates, distance.matrix = NULL, name = NULL,
  comment = NULL, membership = NULL, edge.weight.type = NULL,
  depot.coordinates = NULL, lower = NULL, upper = NULL,
  opt.tour.length = NULL, opt.tour = NULL, get.distances = TRUE)

Arguments

coordinates	[matrix] Numeric matrix of 2D coordinates.
distance.matrix	[matrix] Optional distance matrix.
name	[character(1) | NULL] Optional name of the network.
comment	[character | NULL] Optional additional comments on instance.
membership	[numeric | NULL] Optional vector of memberships for clustered networks.
edge.weight.type	[character(1) | NULL] The edge weight type indicates how edge weights are represented in the TSPlib format. If distance.matrix is NULL, the passed value is ignored and EUC\_2D is assigned. Otherwise the edge weight type must be one of the following {EUC\_2D, EUC\_3D, MAX\_2D, MAX\_3D, MAN\_2D, MAN\_3D, CEIL\_2D, GEO, ATT, EXPLICIT}.
depot.coordinates	[matrix | NULL] Numeric matrix of 2D coordinates of depots. Default is NULL, which means no depots at all.
lower	[numeric(1)] Lower box constraint of cube.
upper	[numeric(1)] Upper box constraint of cube.
opt.tour.length	[numeric(1)] Optional length of the optimal roundtrip tour. Default is NULL, which means the tour length is unknown.
opt.tour	[integer] Optional optimal permutation of node indizes. Default is NULL, which means the optimal tour is unknown.
get.distances	[logical(1)] Should distances be loaded? For really large instances the distance matrix may be very large. In certain situations it is thus desirable to load the instance without loading/generating the distance matrix itself. Default is TRUE.

Value

[Network]
