gvgen − generate graphs
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 ]
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. | ||
|
−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. |
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.
