Unfortunately, no. I've never used it.

So, boost is exactly 1/2 of networkx's solution.

I would guess that the difference has to do with networkx's normalization of
between values, but I couldn't say for certain. It might also be that
networkx is following undirected edges twice, resulting in twice the value.
That would definitely be worth looking into.
