Sen Pei, Jiannan Wang, Flaviano Morone, Hernán A Makse
2019 arXiv   pre-print
In particular, we first discuss the problem of finding the minimal number of nodes whose removal would breakdown the network (i.e., the optimal percolation or network dismantle problem), and then survey  ...  The integrity and functionality of many real-world complex systems hinge on a small set of pivotal nodes, or influencers.  ...  In Section 3, we discuss the progresses in optimal percolation using collective influence, optimal decycling, explosive percolation and large deviations of percolation in details.  ...
