Looking into Complex Networks

This article summaries the discussions about the open issues and research tendency of complex networks by several active scholars.The statement covers both fundamental problems like the understand-ing of power-law degree distributions,the underlying connections between different flow-driven dynamics and the mechanism leading to acceleratingly growing,and the in-depth analyses like the understanding of mesoscales in complex networks.Moreover,we introduce some typical interdisciplinary studies where complex networks play a major role,including the link prediction in complex networks,recommender systems for user-object bipartite networks,the integration of cyber physical systems and complex networks,the human dynamics in the online network space,and the possibly important role of the studies of complex networks in national security.
