Special Issue of the 9th International Conference on Complex Networks and Their Applications

New Content Item

Since 2012, the International Conference on Complex Networks and Their Applications (COMPLEX NETWORKS) brings together researchers from different scientific communities working on areas related to Network Science in order to cross-fertilize ideas among scientists, For the ninth edition of this annual event, 362 submissions have been received from around the world. The contributions selected for submission to this special issue reflect the latest problems, advances, and diversity within the Network Science community.
