Pynauty

Version 1.0

by Sam Morley-Short

This is a fork of pynauty--a Python extension of the C module nauty--to add extra features needed for exploring LC classes of quantum graph states. Specifically, this fork adds a function used for canonical graph labelling such that any two isomorphic graphs have the same canonical node labelling.

This fork was made entirely for use by the package Graph State Compass (gsc), which can be found here. It is redistributed under the GPL v3 copyleft lisence WITHOUT ANY WARRANTY.

To install, follow the instructions provided here.

Loosely, this requires:

1. Downloading nauty, (working as of version 27b11, found here),
2. Unzipping it and placing it in the top-level of this repo (e.g. /pynauty),
3. Symbolic link the nauty directory to /nauty (for the above case on Mac OS X this means running ln -s nauty27b11 nauty from the command line),
4. Installing pynauty (make user-ins can be used to install globally).
