Before revision:  This also distinguishes the two directed networks of incoming and outgoing links from each other. The initial condition for a dynamic model, evolving towards the steady dependency distribution , determines the saturation properties of the mature scale-free network .
After revision:  This also distinguishes the two directed networks of incoming and outgoing links . Dynamic evolution, over two generations of free software releases, shows that the saturation properties of the in-directed and out-directed networks are oppositely affected. For the out-degree distribution, whose top nodes form the foundation of the entire network, the initial condition for a dynamic model, evolving towards the steady dependency distribution , determines the saturation properties of the mature scale-free network .
