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)

              With -z, #-in #-out digraph without loops

              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 for #*n steps 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
