These days most people use nauty via a +larger package such as Magma, Sage, or GAP, and often they don't +even know they are using nauty. Due to the legal nonsense that +large package distributors need to worry about, it has proved too +much trouble to maintain an idiosyncratic licence. I didn't change +my opinion about military use, but it is no longer part of the +formal notice. Brendan McKay (Jan 20, 2016) |
