New Journal of Physics Analysis of the structure of complex networks at different resolution levels

doi:10.1088/1367-2630/10/5/053039 Abstract. Modular structure is ubiquitous in real-world complex networks, and its detection is important because it gives insights into the structure–functionality relationship. The standard approach is based on the optimization of a quality function, modularity, which is a relative quality measure for the partition of a network into modules. Recently, some authors (Fortunato and Barthélemy 200
