makeNetwork

Generate network based on coordinates.

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, node.weights = NULL)

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.
node.weights

[numeric]
Vector of node weights (for weighted version of TSP). Default is NULL, i.e., no node weights at all.

Value
