Inequalities for the curvature of curves and surfaces
In this paper, we bound the difference between the total mean curvatures of two closed surfaces in R3 in terms of their total absolute curvatures and the Fr´echet distance betwee...

Competitive analysis of organization networks or multicast acknowledgement: how much to wait?
We study, from the competitive analysis perspective, the trade off between communication cost and delay cost (or simply the sendor-wait dilemma) on a hierarchy (rooted tree). The p...

Fault-oriented Test Generation for Multicast Routing Protocol Design
Abstract: We present a new algorithm for automatic test generation for multicast routing. Our algorithm processes a nite state machine (FSM) model of the protocol and uses a mix of...

Towards worst-case churn resistant peer-to-peer systems
Abstract Until now, the analysis of fault tolerance of peerto-peer systems usually only covers random faults of some kind. Contrary to traditional algorithmic research, faults as w...
