Authors project page identifies nauty and Traces as graph/digraph automorphism and canonical-labeling programs. Title/byline Brendan McKay and Adolfo Piperno; Documentation links the authors user guide and Practical Graph Isomorphism.

Author-maintained ANU mirror: users.cecs.anu.edu.au/~bdm/nauty/ . Summary identifies automorphism-group and canonical-labeling functionality and the included gtools suite; Documentation links the original1981 nauty design, Piperno’s Traces paper and the current joint algorithms paper. The linked manual is users.cecs.anu.edu.au/~bdm/nauty/nug29.pdf .

arXiv:1301.1493, submitted8January2013. Primary manuscript arxiv.org/pdf/1301.1493 , title-page bylines and affiliations; introduction and algorithmic framework describe graph isomorphism, automorphisms, canonical labeling and individualization/refinement; subsequent sections discuss nauty, Traces and experimental comparisons.

arXiv:0804.4881, submitted30April2008, version2 dated26January2011. Primary manuscript arxiv.org/pdf/0804.4881 , title-page byline and introduction describe Traces, equitable partitions, individualization and contraction of the search space, followed by algorithmic and experimental comparisons.
