Odd Cycle Packing
We study the ratio between the minimum size of an odd cycle vertex transversal and the maximum size of a collection of vertex-disjoint odd cycles in a planar graph. We show that th...

Finding good cycle constraints for large scale multi-robot SLAM
Abstract— In this paper we describe an algorithm to compute cycle constraints that can be used in many graph-based SLAM algorithms; we exemplify it in Hierarchical SLAM. Our algo...

Mesh Median Filter for Smoothing 3-D Polygonal Surfaces
In this paper, we introduce a new mesh filtering method: a mesh median filter. This is an application of the median filter to smoothen 3-D noisy shapes given by triangle meshes...

Efficient Sequential and Parallel Algorithms for the Negative Cycle Problem
We present here an algorithm for detecting (and outputting, if exists) a negative cycle in an n-vertex planar digraph G with real

Convergence of the multigrid $V$-cycle algorithm for second-order boundary value problems without full elliptic regularity
The multigrid V -cycle algorithm using the Richardson relaxation scheme as the smoother is studied in this paper. For second-order elliptic boundary value problems, the contraction...
