cliquer - find cliques in weighted and unweighted graphs. SYNOPSIS
cliquer --help cliquer [ options ] graph-filename DESCRIPTION
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. OPTIONS
-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. FILE FORMAT
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. EXAMPLE

cluster - find clusters in a graph and augment the graph with this information. SYNOPSIS
cluster [-v?] [ -Ck ] [ -ck ] [ -o outfile ] [ files ] DESCRIPTION
cluster takes as input a graph in DOT format, finds node clusters and augments the graph with this information. The clusters are specified by the "cluster" attribute attached to nodes; cluster values are non-negative integers. cluster attempts to maximize the modularity of the clustering. If the edge attribute "weight" is defined, this will be used in computing the clustering. OPTIONS
The following options are supported: -Ck specifies a targeted number of clusters that should be generated. The specified number k is only a suggestion and may not be real- isable. If k == 0, the default, the number of clusters that approximately optimizes the modularity is returned. -ck specifies clustering method. If k == 0, the default, the modularity will be used. If k == 1 modularity quality will be used. -ooutfile Specifies that output should go into the file outfile. By default, stdout is used. -v Verbose mode. EXAMPLES
Applying cluster to the following graph, graph { 1--2 [weight=10.] 2--3 [weight=1] 3--4 [weight=10.] 4--5 [weight=10] 5--6 [weight=10] 3--6 [weight=0.1] 4--6 [weight=10.] } gives graph { node [cluster="-1"]; 1 [cluster=1]; 2 [cluster=1]; 3 [cluster=2]; 4 [cluster=2]; 5 [cluster=2]; 6 [cluster=2]; 1 -- 2 [weight="10."]; 2 -- 3 [weight=1]; 3 -- 4 [weight="10."]; 4 -- 5 [weight=10]; 5 -- 6 [weight=10]; 3 -- 6 [weight="0.1"]; 4 -- 6 [weight="10."]; } AUTHOR
