bliss — Compute automorphism groups and canonical labelings of graphs

## Synopsis

**bliss** [*OPTIONS*] [<*GRAPH FILE*>]

## Description

Bliss is an open source tool for computing automorphism groups and canonical forms of graphs. The graphs are specified in DIMACS format.

**-directed**the input graph is directed

**-can**compute canonical form

**-ocan**=*f*compute canonical form and output it in file

*f***-v**=*N*set verbosity level to N [N >= 0, default: 1]

**-sh**=*X*select splitting heuristics, where X is:

f first non-singleton cell fl first largest non-singleton cell fs first smallest non-singleton cell fm first maximally non-trivially connected non-singleton cell flm first largest maximally non-trivially connected non-singleton cell fsm first smallest maximally non-trivially connected non-singleton cell (default) **-fr**=*X*use failure recording? [X=y/n, default: y]

**-cr**=*X*use component recursion? [X=y/n, default: y]

**-version**print the version number and exit

**-help**print this help and exit
