cliquer — Find cliques in arbitrary weighted graphs

## Synopsis

**cliquer** [*OPTION*]... <*DIMACS_FILE*>

## Description

Cliquer is a set of C routines for finding cliques in an arbitrary weighted graph. It uses an exact branch-and-bound algorithm developed by Patric Östergård. It is designed with the aim of being efficient while still being flexible and easy to use.

## Options

**-h**,**--help**- Print the help text.
**-a**,**--all**- Find all cliques.
**-s**,**--single**- Find a single clique (the 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). Positive N 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 from 0 to n-1 instead of 1 to n when writing.
**-r**F,**--reorder**F- Reorder with function F. The available functions are:
- none
- No ordering (same order as in the file).
- reverse
- Reverse of the order in the file.
- default
- Either unweighted-coloring or weighted-coloring, 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.

**-q**,**--quiet**- Suppresses progress output. Specifying -q twice suppresses all output except the actual result.
