Justification-Based Non-Clausal Local Search for SAT
While stochastic local search (SLS) techniques are very efficient in solving hard randomly generated propositional satisfiability (SAT) problem instances, a major challenge is to i...

Removing Local Extrema from Imprecise Terrains
In this paper, we study imprecise terrains, that is, triangulated terrains with a vertical error interval in the vertices. We study the problem of removing as many local extrema (...

On optimal temporal locality of stencil codes
Iterative solvers such as the Jacobi and Gauss-Seidel relaxation methods are important, but time-consuming building blocks of many scientific and engineering applications. The per...

Gaussian mixture modeling for source localization
Exploiting prior knowledge, we use Bayesian estimation to localize a source heard by a fixed sensor network. The method has two main aspects: Firstly, the probability density fun...
