NAME
       gvgen - generate graphs

SYNOPSIS
       gvgen  [	 -d?   ] [ -cn ] [ -Cx,y ] [ -g[f]x,y ] [ -G[f]x,y ] [ -hn ] [
       -kn ] [ -bx,y ] [ -pn ] [ -sn ] [ -Sn ] [ -tn ] [ -Tx,y ]  [  -wn  ]  [
       -ooutfile ]

DESCRIPTION
       gvgen  generates	 a  variety  of	 simple, regularly-structured abstract
       graphs.

OPTIONS
       The following options are supported:

       -c n   Generate a cycle with n vertices and edges.

       -C x,y Generate an x by y cylinder.  This will have  x*y	 vertices  and
	      2*x*y - y edges.

       -g [f]x,y
	      Generate	an  x  by  y grid.  If f is given, the grid is folded,
	      with an edge attaching each pair of  opposing  corner  vertices.
	      This  will have x*y vertices and 2*x*y - y - x edges if unfolded
	      and 2*x*y - y - x + 2 edges if folded.

       -G [f]x,y
	      Generate an x by y partial grid.	If f is	 given,	 the  grid  is
	      folded, with an edge attaching each pair of opposing corner ver‐
	      tices.  This will have x*y vertices.

       -h n   Generate a hypercube of degree n.	 This will have	 2^n  vertices
	      and n*2^(n-1) edges.

       -k n   Generate a complete graph on n vertices with n*(n-1)/2 edges.

       -b x,y Generate	a complete x by y bipartite graph.  This will have x+y
	      vertices and x*y edges.

       -p n   Generate a path on n vertices.  This will have n-1 edges.

       -s n   Generate a star on n vertices.  This will have n-1 edges.

       -S n   Generate	a  Sierpinski  graph  of  order	 n.   This  will  have
	      3*(3^(n-1) - 1)/2 vertices and 3^n edges.

       -t n   Generate	a  binary tree of height n.  This will have 2^n-1 ver‐
	      tices and 2^n-2 edges.

       -T x,y Generate an x by y torus.	 This will have x*y vertices and 2*x*y
	      edges.

       -w n   Generate a path on n vertices.  This will have n-1 edges.

       -o outfile
	      If  specified, the generated graph is written into the file out‐
	      file.  Otherwise, the graph is written to standard out.

       -d     Make the generated graph directed.

       -?     Print usage information.

EXIT STATUS
       gvgen exits with 0 on successful completion, and exits with 1 if	 given
       an  ill-formed or incorrect flag, or if the specified output file could
       not be opened.
