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 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. -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 vertices 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 outfile. 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. AUTHOR
