The robustness of the infrastructure of various real-life systems, which can be represented
by networks and manifests the scale-free property, is of great importance. Thus, in this …

The essential of existing methods for promoting network robustness is randomly exchanging
the edges of networks. Without considering the network structure, the performance of these …

In a recent work [Schneider, Proc. Natl. Acad. Sci. USA 108, 3838 (2011) PNASA6 0027-
8424 10.1073/pnas. 1009440108], the authors proposed a simple measure for network …

Networked systems exist broadly in daily life and have been greatly emphasized in recent
studies. Since these networks are always exposed in complicated environments and may …

Error tolerance and attack vulnerability are two common and important properties of complex
networks, which are usually used to evaluate the robustness of a network. Recently, much …

The threat of a malicious attack is one of the major security problems in complex networks.
Resilience is the system-level self-adjusting ability of a complex network to retain its basic …

We study the robustness of Barabási-Albert scale-free networks with respect to intentional
attacks to highly connected nodes. Using the simulated annealing optimization heuristic, we …

The invulnerability of complex networks is an important issue in that the behavior of scale-
free network differs from that of exponential network. According to the structural …

The robustness is an important functionality of networks because it manifests the ability of
networks to resist failures or attacks. Many robustness measures have been proposed from …

The problem of finding the best strategy to attack a network or immunize a population with a
minimal number of nodes has attracted much current research interest. The assessment of …
