Comment (by ncohen):
Hello,
Nice code, it is simple and does the job. At the same time that an error
has been reported in the implementation of `is_interval_graph`, it is
almost tempting to replace our current implementation of it by `is_chordal
and is_AT_Free` `;-)`
I will fix it soon, though. And I will probably need your help for the
review.
About this branch: it is a bit weird to expose only a version of
`is_at_free` that does not allow for a `certificate=True` flag, given that
other recognition algorithms have it. Also, could you turn `AT` into
`asteroidal_triple` in the functions' name ? We try to avoid abbreviations
in Sage.
After this, I guess that I should be able to add a commit and we will be
done here. I am a bit troubled by your "parameters": why not "input" ?
Good night,
Nathann
