[igraph] Barabási-Albert model

[Guilherme Ferraz de Arruda]

Hi everybody,

I noticed a problem on the function igraph_barabasi_game(). I used the parameter algo as IGRAPH_BARABASI_PSUMTREE and I got some assortative networks. I was trying to genetate some Barabási-Albert model, with linear preferential attachment.

This kind of models could not be assortative, the assortativity must be close to zero.

Is this a problem on igraph or did I just make some mistake?

Thanks for all.

Guilherme.
