[igraph] references

[Guilherme Ferraz de Arruda]

Hi,

I'm searching for the references for the Games, Randomized Graph Generators.
Specialy for this 2 functions:
igraph_recent_degree_aging_game — Preferential attachment based on the
number of edges gained recently, with aging of vertices
igraph_recent_degree_game — Stochastic graph generator based on the
number of adjacent edges a node has gained recently

What are the authors that sugested this models? In what papers?

Thanks for all.

Guilherme.
