ISGCI lists a lot of graph classes, many of which are recognizable in polynomial time. Is anyone here aware of actual implementations of these algorithms?

This question lists a bunch of graph manipulation packages. Maybe one of them: mathoverflow.net/questions/26231/… –  supercooldave Jul 2 '10 at 20:29
If you mean, is there freely available, reasonable quality code, then I believe the answer is no. As far as I understand, algorithms for some of the ISGCI classes have been implemented, but typically these are rough-and-ready prototypes. –  András Salamon Jul 29 '10 at 12:33
