history
Project history and usage
nauty and Traces are graph isomorphism, automorphism group, and canonical labelling tools by Brendan McKay and Adolfo Piperno. They are foundational academic software for graph theory and combinatorics, with command-line utilities as well as C APIs.
Project history
The official site roots nauty's original design in Brendan McKay's 1981 paper 'Practical Graph Isomorphism'. It lists Traces' original design in Adolfo Piperno's work on search-space contraction and cites McKay and Piperno's 2014 'Practical Graph Isomorphism, II' paper for the current algorithms.
The package has accumulated a large utility suite around the core algorithms. The official site describes gtools, including `geng` for rapidly generating non-isomorphic graphs, plus generators and file-manipulation programs for graph6, sparse6, and related compact graph formats.
Adoption history
nauty is widely embedded in mathematical software and research workflows. The official license note says many people use nauty through larger packages such as Magma, Sage, or GAP, sometimes without knowing it. Homebrew analytics consulted on 2026-07-01 listed 867 installs over the preceding 365 days, which is modest for a general CLI but meaningful for specialized computational mathematics software.
How it is used
Package users run utilities such as `dreadnaut`, `geng`, `labelg`, `shortg`, `countg`, and `showg`, or compile programs against the C interfaces. The user guide says `dreadnaut` is enough for many one-off computations, while serious use usually means writing a program that calls nauty or Traces directly.
Why package nerds care
For package people, nauty is a classic case where the executable list is the product: installing the package gives a graph-processing toolbox, not a single app. It is also a dependency hiding under higher-level math systems, so packaging it correctly improves reproducibility for many graph enumeration and isomorphism workloads.
Timeline
- 1981: McKay's original 'Practical Graph Isomorphism' paper published.
- 2008: Traces source files listed with Adolfo Piperno copyright beginning in 2008.
- 2014: McKay and Piperno's 'Practical Graph Isomorphism, II' published in Journal of Symbolic Computation.
- 2016-02-26: nauty and Traces 2.5 release noted on the official site.
- 2026-01-01: Version 2.9.3 released on the official site.
Related projects
- Magma, Sage, GAP, graph6/sparse6 tooling, Graphviz via `dretodot`, and graph-isomorphism research code are closely related.
