The convergence is guaranteed by the values of alpha and beta alone. One could force convergence some way or another, but then it would no longer be the Katz centrality, but some other variant. > There is another normalization on the _init.py file before the C++ BGL > function call, line 738. This is the only (optional) normalization left in the code. I removed the normalization from the C++ part. Cheers, Tiago -- Tiago de Paula Peixoto <[email protected]>
