Hi,

I'm a bit confused with the definition of normalized betweenness centrality

in the documentation:

http://projects.forked.de/graph-tool/wiki/BetweennessCentrality#BetweennessCentrality

Basically, I'm looking at Freedman, Sociometry 40 (1), 35-41 and at the

boost graph library page:

http://www.boost.org/libs/graph/doc/betweenness_centrality.htmlBoth the paper and the boost web pages mention a normalization factor of

(n-1)(n-2)/2. However the 1/2 factor seems to be missing from the graph-tool

documentation -is this just a documentation typo?

Cheers,

Rui
