Subspace Approximation with Outliers,mic results for robust subspace recovery require strong assumptions on the input, e.g., any . outliers must be linearly independent..In this paper, we show how to extend dimension reduction techniques and bi-criteria approximations based on sampling and coresets to the problem of subspace approximat

An Optimal Lower Bound for Hierarchical Universal Solutions for TSP on the Plane,esgue and Peano curves..Our main result is a lower bound of . on the competitive ratio of any Universal TSP tour using hierachical orderings. This is an improvement for this setting on the best known lower bound for Universal TSP on the plane for arbitrary orderings of . due to Hajiaghayi . [., 649–

Linear-Time Algorithms for Eliminating Claws in Graphs, the distance of a given graph to a claw-free graph, considering vertex elimination as measure. . consists of determining the minimum number of vertices to be removed from a graph such that the resulting graph is claw-free. Although . is .-complete in general and recognizing claw-free graphs is stil

Bounded-Degree Spanners in the Presence of Polygonal Obstacles,ity graph of . with respect to .. As this graph can have unbounded degree, we modify it in three easy-to-follow steps, in order to bound the degree to 7 at the cost of slightly increasing the spanning ratio to 6.
