Computing stable models in parallel
Answer-set programming (ASP) solvers must handle difficult computational problems that are NP-hard. These solvers are in the worst case exponential and their scope of applicabilit...

Momentum Based Optimization Methods for Level Set Segmentation
Abstract. Segmentation of images is often posed as a variational problem. As such, it is solved by formulating an energy functional depending on a contour and other image derived t...

An Efficient Algorithm for 2D Euclidean 2-Center with Outliers
For a set P of n points in R2 , the Euclidean 2-center problem computes a pair of congruent disks of the minimal radius that cover P. We extend this to the (2, k)-center problem wh...
