A Modified Simulation Environment for Reconfigurable Multicomputer Systems in Digital Image Processing Applications
In our work we improve the EPPI programming environment, which was made in the University of Castilla - la Mancha one year ago. EPPI is a tool for simulating parallel algorithms t...

Interval Arithmetic with Containment Sets
The idea of containment sets (csets) is due to Walster and Hansen, and the theory is mainly due to the first author. Now that floating point computation with infinities is widely a...

H-LLL: using householder inside LLL
We describe a new LLL-type algorithm, H-LLL, that relies on Householder transformations to approximate the underlying Gram-Schmidt orthogonalizations. The latter computations are ...

Output-sensitive algorithms for Tukey depth and related problems
The Tukey depth (Tukey 1975) of a point p with respect to a finite set S of points is the minimum number of elements of S contained in any closed halfspace that contains p. Algori...
