Complex Networks

Lead Guest Editor: Hocine Cherifi

Real-world entities often interconnect with each other through explicit or implicit relationships to form complex networks, such as engineering systems, economic systems, and social systems. This special issue is a collection of papers dealing with theoretical tools and methods used in applications as well as practical problems from network science.

  1. The retweet is a characteristic mechanism of several social network services/social media, such as Facebook, Twitter, and Weibo. By retweeting tweet, users can share an article with their friends and followers...
