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.
-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 ver-
tices 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 avail-
able if the -R flag is used.
-n prefix
Normally, integers are used as node names. If prefix is speci-
fied, 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 out-
file. 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.
