On Multidimensional k-Anonymity with Local Recoding Generalization
This paper presents the first theoretical study, on using local-recoding generalization (LRG) to compute a kanonymous table with quality guarantee. First, we prove that it is NP-h...

Local algorithms in (weakly) coloured graphs
A local algorithm is a distributed algorithm that completes after a constant number of synchronous communication rounds. We present local approximation algorithms for the minimum ...

Resource Allocation Strategies in a 2-Level Hierarchical Grid System
Efficient job scheduling in grids is challenging due to the large number of distributed autonomous resources. In this paper we study various resource allocation policies in a 2-le...

Depth-First Branch-and-Bound versus Local Search: A Case Study
Depth-first branch-and-bound (DFBnB) is a complete algorithm that is typically used to find optimal solutions of difficult combinatorial optimization problems. It can also be adap...

Combining hierarchical radiosity and discontinuity meshing
We introduce a new approach for the computation of viewindependent solutions to the diffuse global illumination problem in polyhedral environments. The approach combines ideas fro...
