Welcome to the Complex Networks Analysis discussion group


The Complex Network Analysis (CNA) discussion group aims to bring together scientists from different groups and teams of the Institute that want to share research ideas, experimental results, expertise, and knowledge around the area of Complex Networks, probabilistic graphs, and related research topics.

In this context, discussions and presentations will take place twice a month.
