“…Global organization patterns of large complex networks involve the presence of structural sub-units (subnetworks) that have been called communities or modules , broadly defined as subsets of tightly interconnected nodes so that the density of within-connections is higher than that of between-connections (Girvan and Newman, 2002 ; Porter et al, 2009 ; Fortunato, 2010 ). Module detection in networks, is still an open problem in computer science (Mucha et al, 2010 ) and there is an important variety of methods and algorithms to detect such communities (Gulbahce and Lehmann, 2008 ; Ahn et al, 2010 ; Fortunato, 2010 ; Xie et al, 2013 ; Fortunato and Hric, 2016 ); thus, modular structure is an issue of particular relevance, from economic and social systems (Espinal-Enríquez et al, 2015b ; García-Pérez et al, 2016 ), to biological systems (Alcalá-Corona et al, 2016 ).…”
