NAME

v.net.salesman - Create a cycle connecting given nodes (Traveling salesman problem). Note that TSP is NP-hard, heuristic algorithm is used by this module and created cycle may be sub optimal.

KEYWORDS

vector, networking

SYNOPSIS

v.net.salesman
v.net.salesman help
v.net.salesman [-g] input=name output=name [type=string[,string,...]] [alayer=integer] [nlayer=integer] [acolumn=string] ccats=range [--overwrite]

Flags:

-g
Use geodesic calculation for longitude-latitude locations
--overwrite
Force overwrite of output files

Parameters:

input=name
Name of input vector map
output=name
Name for output vector map
type=string[,string,...]
Arc type
Options: line,boundary
Default: line,boundary
alayer=integer
Arc layer
Default: 1
nlayer=integer
Node layer (used for cities)
Default: 2
acolumn=string
Arcs' cost column (for both directions)
ccats=range
Category values
Categories of points ('cities') on nodes (layer is specified by nlayer)

DESCRIPTION

v.net.salesman calculates the optimal route to visit nodes on a vector network.
