NAUTY-GENRANG

NAME

nauty-genrang - generate random graphs

SYNOPSIS

genrang [-P#|-P#/#|-e#|-r#|-R#|-d#] [-M#] [-l#] [-m#] [-t] [-T] [-a] [-s|-g|-z] [-S#] [-q] n|n1,n2 num [outfile]

DESCRIPTION

Generate random graphs.

n

: number of vertices

n1,n2 : number of vertices (bipartite graph)

num : number of graphs

A bipartite variant is only available if specified below.

	-s	: Write in sparse6 format (default)
	-g	: Write in graph6 format
	-z	: Make random digraphs and write in digraph6 format
	-P#/# :

Give edge probability; -P# means -P1/#.

Bipartite version available.

-e# : Give the number of edges

Bipartite version available.

	-r# : Make regular of specified degree
	-d# : Make regular of specified degree (pseudorandom)

Bipartite version: this is the degree on the first side.

-M# : In conjunction with -d, make the distribution more uniform

by running a Markov chain starting at the pseudorandom graph.

-R# : Make regular of specified degree but output

as vertex count, edge count, then list of edges

	-l# : Maximum loop multiplicity (default 0)
	-m# : Maximum multiplicity of non-loop edge (default and minimum 1)
	-t

: Make a random spanning tree of a complete graph

or complete bipartite graph

	-T		: Make a random tournament (implies -z)
	-a		: Make invariant under a random permutation
	-S# :

Specify random generator seed (default nondeterministic)

	-q
			: suppress auxiliary output
