Reasoning over Extended ER Models
Abstract. We investigate the computational complexity of reasoning over various fragments of the Extended Entity-Relationship (EER) language, which includes a number of constructs:...

Higher Lower Bounds for Near-Neighbor and Further Rich Problems
We convert cell-probe lower bounds for polynomial space into stronger lower bounds for near-linear space. Our technique applies to any lower bound proved through the richness meth...

A Statistical Framework for Intrusion Detection in Ad Hoc Networks
— We focus on detecting intrusions in ad hoc networks using the misuse detection technique. We allow for detection modules that periodically fail to detect attacks and also gener...

Distributed algorithm for a color assignment on asynchronous rings
We study a version of the β-assignment problem [3] on asynchronous rings: consider a set of items and a set of m colors, where each item is associated to one color. Consider also...

Using SAT in QBF
QBF is the problem of deciding the satisfiability of quantified boolean formulae in which variables can be either universally or existentially quantified. QBF generalizes SAT (S...
