This international workshop on complex networks (CompleNet) aims at bringing together researchers and practitioners working on areas related to complex networks. In the past two decades we have been witnessing an exponential increase on the number of publications in this field. From biological systems to computer science, from economic to social systems, complex networks are becoming pervasive in many fields of science. It is
this interdisciplinary nature of complex networks that CompleNet aims at addressing.

Workshops are scheduled around the world on an yearly basis. The first edition of the workshop took place in May 2009 in Catania, Italy; the 2nd took place in Rio de Janeiro, Brazil; the 3rd in Melbourne, Florida, USA; 4th in Berlin, Germany. This year the conference will take place in Bologna, Italy.
