Graph canonical labeling and automorphism group computation
Description
Nauty and Traces are programs for computing automorphism groups of
graphs and digraphs. (At present, Traces does not accept digraphs.)
They can also produce a canonical label. They are written in a portable
subset of C, and run on a considerable number of different systems.
There is a small suite of programs called gtools included in the
package. For example, geng can generate non-isomorphic graphs very
quickly. There are also generators for bipartite graphs, digraphs, and
multigraphs, and programs for manipulating files of graphs in a compact
format.
