Using arborescences to estimate hierarchicalness in directed complex networks

Complex networks are a useful tool for the understanding of complex systems. One of the emerging properties of such systems is their tendency to form hierarchies: networks can be organized in levels ... complex networks. Many complex systems tend to organize themselves in different levels, increasingly centralized [4, 5]. Previous works have identified three different types of hierarchy: order, nested and
