This is the command cliquer that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
cliquer - find cliques in weighted and unweighted graphs.
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.
Displays a short list of options and what they do.
Find all cliques.
Find only one clique (default).
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).
Require cliques to be maximal.
Assume weight 1 for all vertices.
Number vertices 0 to n-1 instead of 1 to n when writing.
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 order as in the file.
One of the two below, depending on weightedness.
Coloring method efficient for unweighted graphs.
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
A line with 'e' adds an edge. The two next tokens are the numbers of two nodes to
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.
