cliquer - find cliques in weighted and unweighted graphs.
cliquer --help cliquer [ options ] graph-filename
cliquer searched for cliques in a graph. The graph is read from the file given as command line argument, or stdin if that filename is "-". The file must be ASCII as described below or a binary DIMACS-format. By default it prints the first maximal clique it finds, but this can be changed with the options described below.
-h --help Displays a short list of options and what they do. -a --all Find all cliques. -s --single Find only one clique (default). -w --weight Tell only maximum weight (no faster than -s). -m N --min N Search for cliques with weight at least N. If N=0, searches for maximum weight clique (default). -M N --max N Search for cliques with weight at most N. If N=0, no limit is imposed (default). N being positive is incompatible with "--min 0" ("--min 1" is assumed). -x --maximal Require cliques to be maximal. -u --unweighted Assume weight 1 for all vertices. -0 --from-0 Number vertices 0 to n-1 instead of 1 to n when writing. -q --quiet Suppresses progress output. Specifying -q twice suppresses all output except the actual result. -r F --reorder F Reorder with function F. Available reordering functions are: none No ordering (same order as in the file). reverse Reverse order as in the file. default One of the two below, depending on weightedness. unweighted-coloring Coloring method efficient for unweighted graphs. weighted-coloring Coloring method efficient for weighted graphs. degree Order by ascending degree. random Random order.
The format of the ASCII representation of a graph is the following: Each line has a single letter (enclosed in spaces) as first part. A line with 'p' starts the graph. The second token is a name of at most 15 characters and ignored. Then there is the number of nodes in this graph. Then the number of edges (currently ignored). A line with 'e' adds an edge. The two next tokens are the numbers of two nodes to connect. A line with 'n' weights an node. The first argument is the number of the node to assign a weight to, the second it's weight.
