High-Performance Algorithm Engineering for Computational Phylogenetics
Abstract. Phylogeny reconstruction from molecular data poses complex optimization problems: almost all optimization models are NP-hard and thus computationally intractable. Yet app...

Multi-dimensional Resource Scheduling for Parallel Queries
Scheduling query execution plans is an important component of query optimization in parallel database systems. The problem is particularly complex in a shared-nothing execution en...

Bounds for Nonadaptive Group Tests to Estimate the Amount of Defectives
The classical and well-studied group testing problem is to find d defectives in a set of n elements by group tests, which tell us for any chosen subset whether it contains defectiv...

MMSE Based Transceiver Designs in Closed-Loop Non-Regenerative MIMO Relaying Systems
In this paper, we propose a new design strategy based on the minimum mean-squared error (MMSE) in closedloop non-regenerative multiple-input multiple-output (MIMO) relaying system...

Sharing work in keyword search over databases
An important means of allowing non-expert end-users to pose ad hoc queries — whether over single databases or data integration systems — is through keyword search. Given a set...
