Comment (by borassi):
Hellooooo!
Great, now the algorithm should be much faster!
I think there is still a problem with directed graphs: the Takes-Kosters
algorithm works only on undirected graphs, so I think you should add a
`ValueError` if the user asks the Takes-Kosters algorithm on directed
graphs. I would add at the top of c_eccentricity_bounding
{{{
if G.is_directed():
raise ValueError("The bounds method only works on undirected graphs.")
}}}
After you correct this, I will try to perform a more extensive testing,
and I will provide a positive review!
