Priorities of Attack on Urban Problems

Priorities in Urban Traffic Problems and Implications for the Design of Solutions

The introduction of ICT in the traffic domain showed great potential, but the many opportunities this brings seems to have distracted engineers. To solve urban traffic problems, many potentially effective solutions have been developed, but deployment rates are low. The main reason seems to be that stakeholder interests are often not understood. Moreover, a common understanding of the severity o...

A Probabilistic Attack on NP-complete Problems

Using the probability theory-based approach, this paper reveals the equivalence of an arbitrary NPcomplete problem to a problem of checking whether a level set of a specifically constructed harmonic cost function (with all diagonal entries of its Hessian matrix equal to zero) intersects with a unit hypercube in many-dimensional Euclidean space. This connection suggests the possibility that meth...

On DDoS Attack Related Minimum Cut Problems

In this paper, we study two important extensions of the classical minimum cut problem, called Connectivity Preserving Minimum Cut (CPMC) problem and Threshold Minimum Cut (TMC) problem, which have important applications in largescale DDoS attacks. In CPMC problem, a minimum cut is sought to separate a of source from a destination node and meanwhile preserve the connectivity between the source a...

Attack-norm separation for detecting attack-induced quality problems on computers and networks

Cyber attacks on computer and network systems induce system quality and reliability problems, and present a significant threat to the computer and network systems that we are heavily dependent on. Cyber attack detection involves monitoring system data and detecting the attack-induced quality and reliability problems of computer and network systems caused by cyber attacks. Usually there are ongo...
