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