generate graphs

SYNOPSIS

gvgen [ -dv? ] [ -in ] [ -cn ] [ -Cx,y ] [ -g*[f]x,y* ] [ -G*[f]x,y* ] [ -hn ] [ -kn ] [ -bx,y ] [ -Bx,y ] [ -mn ] [ -Mx,y ] [ -pn ] [ -rx,y ] [ -Rx ] [ -sn ] [ -Sn ] [ -Sn,d ] [ -tn ] [ -td,n ] [ -Tx,y ] [ -Tx,y,u,v ] [ -wn ] [ -nprefix ] [ -Nname ] [ -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 vertices. 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.

-B* x,y*
Generate an x by y ball, i.e., an x by y cylinder with two “cap” nodes closing the ends. This will have x*y + 2 vertices and 2*x*y + y edges.

-m* n*
Generate a triangular mesh with n vertices on a side. This will have (n+1)*n/2 vertices and 3*(n-1)*n/2 edges.

-M* x,y*
Generate an x by y Moebius strip. This will have x*y vertices and 2*x*y - y edges.

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

-r* x,y*
Generate a random graph. The number of vertices will be the largest value of the form 2^n-1 less than or equal to x. Larger values of y increase the density of the graph.

-R* x*
Generate a random rooted tree on x vertices.

-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.

-S* n,d*
Generate a d-dimensional Sierpinski graph of order n. At present, d must be 2 or 3. For d equal to 3, there will be 4*(4^(n-1) + 1)/2 vertices and 6 * 4^(n-1) edges.

-t* n*
Generate a binary tree of height n. This will have 2^n-1 vertices and 2^n-2 edges.

-t* h,n*
Generate a n-ary tree of height h.

-T* x,y*
-T* x,y,u,v*
Generate an x by y torus. This will have x*y vertices and 2*x*y edges. If u and v are given, they specify twists of that amount in the horizontal and vertical directions, respectively.

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

-i* n*
Generate n graphs of the requested type. At present, only available if the -R flag is used.

-n* prefix*
Normally, integers are used as node names. If prefix is specified, this will be prepended to the integer to create the name.

-N* name*
Use name as the name of the graph. By default, the graph is anonymous.

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

-d
Make the generated graph directed.

-v
Verbose output.

-?
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.
