A unique challenge in P2P network is that the peer dynamics (departure or failure) cause unavoidable disruption to the downstream peers. While many works have been dedicated to consider fault resilience in peer selection, little understanding is achieved regarding the solvability and solution complexity of this problem from the optimization perspective. To this end, we propose an optimization f...

There is great interest in the topic of resilient cyber systems. However, much of the accompanying research is clouded by a lack of an appropriate definition of the term “resilience” and the challenges of measuring the actual resilience of a system. In this paper, we examine some of the lessons learned in defining resilience metrics and argue that such metrics are highly contextual, and that a ...

Based on panel data of 282 cities in China from 2005 to 2019, this paper constructs an economic resilience evaluation index system three dimensions and applies the entropy value method measure it. The two-stage nested Thiel index, kernel density estimation geographic detector methods are also used explore characteristics their spatial temporal divergence driving factors. We find that Chinese ha...

The resilience of a social-ecological system is measured by its ability to retain core functionality when subjected to perturbation. Resilience is contextually dependent on the state of system components, the complex interactions among these components, and the timing, location, and magnitude of perturbations. The stability landscape concept provides a useful framework for considering resilienc...
