Betweenness-Centrality measure is often used in social and computer communication networks to estimate the potential monitoring and control capabiliti...

Set constraints form a constraint system where variables range over the domain of sets of trees. They give a natural formalism for many problems in pr...

This article determines the weakest failure detectors to implement shared atomic objects in a distributed system with crash-prone processes. We first...

One-dimensional range queries, as one of the most basic type of queries in databases, have been studied extensively in the literature. For large datab...

Abstract. We present a general approach for designing approximation algorithms for a fundamental class of geometric clustering problems in arbitrary d...
