Title: Preferential placement for community structure formation,
Abstract: Various models have been recently proposed to reflect and predict different
properties of complex networks. However, the community structure, which is one
of the most important properties, is not well studied and modeled. In this
paper, we suggest a principle called "preferential placement", which allows to
model a realistic clustering structure. We provide an extensive empirical
analysis of the obtained structure as well as some theoretical results.
