Work-Time Optimal K-Merge Algorithms on the PRAM
The k-merge problem, given a collection of k, (2  k  n), sorted sequences of total length n, asks to merge them into a new sorted sequence. The main contribution of this work is...

k-Anonymity in Databases with Timestamped Data
In this paper we extend the notion of k-anonymity in the context of databases with timestamped information in order to naturally define k-anonymous views of temporal data. We als...

Linear Time Solvable Optimization Problems on Graphs of Bounded Clique Width
Hierarchical decompositions of graphs are interesting for algorithmic purposes. There are several types of hierarchical decompositions. Tree decompositions are the best known ones....

Faster approximation algorithms for the minimum latency problem
We give a 7.18-approximation algorithm for the minimum latency problem that uses only O(n log n) calls to the prize-collecting Steiner tree (PCST) subroutine of Goemans and Willia...

Polynomial time approximation algorithms for multi-constrained QoS routing
We study the multi-constrained Quality-of-Service (QoS) routing problem where one seeks to find a path from a source to a destination in the presence of K 2 additive end-to-end Qo...
