Explosive dismantling of two-dimensional random lattices under betweenness centrality attacks
2021
Abstract In the present paper, we study the robustness of two-dimensional random lattices (Delaunay triangulations) under attacks based on betweenness centrality. Together with the standard definition of this centrality measure, we employ a range-limited approximation known as l -betweenness, where paths having more than l steps are ignored. For finite l , the attacks produce continuous percolation transitions that belong to the universality class of random percolation. On the other hand, the attack under the full range betweenness induces a discontinuous transition that, in the thermodynamic limit, occurs after removing a sub-extensive amount of nodes. This behavior is recovered for l -betweenness if the cutoff is allowed to scale with the linear length of the network faster than l ∼ L 0.91 . Our results suggest that betweenness centrality encodes information on network robustness at all scales, and thus cannot be approximated using finite-ranged calculations without losing attack efficiency.
