[igraph] alpha.centrality with weights problem

[Michael Bishop]

Hello igraph experts!

I am surprised to receive identical output from the following two functions:

alpha.centrality(netList, alpha=0.09, weights=NULL)

and

alpha.centrality(netList, alpha=0.09, weights=E(netList)$weight)

                             

Any idea what is going on?

The weight attribute ranges from 0.6 to 1.

The graph is completely connected though it is directed and some nodes only have incoming and others only outgoing edges.

Many Thanks,

Mike
