  Scale-free networks are abundant in nature and society, describing such
diverse systems as the world wide web, the web of human sexual contacts, or the
chemical network of a cell. All models used to generate a scale-free topology
are stochastic, that is they create networks in which the nodes appear to be
randomly connected to each other. Here we propose a simple model that generates
scale-free networks in a deterministic fashion. We solve exactly the model,
showing that the tail of the degree distribution follows a power law.
