A dynamic -spanner for disk intersection graphs
Sarita de Berg, Ivor van der Hoog, Eva Rotenberg +2
We maintain a -spanner over the disk intersection graph of a dynamic set of disks. We restrict all disks to have their diameter in for some fixed and know…
The Contiguous Art Gallery Problem is in Î(n log n)
Sarita de Berg, Jacobus Conradi, Ivor van der Hoog +1
Recently, a natural variant of the Art Gallery problem, known as the \emph{Contiguous Art Gallery problem} was proposed. Given a simple polygon , the goal is to partition its bo…
Instance and Universally Optimal Bounds for Imprecise Pareto Fronts
Sarita de Berg, Nynne Maria Foldager Bække, Frida Astrup Eriksen +3
In the imprecise geometry model, the input is an imprecise point set, which is a family of regions , where for each one may retrieve the true point $p_…
Exact solutions to the Weighted Region Problem
Sarita de Berg, Guillermo Esteban, Rodrigo I. Silveira +1
In this paper, we consider the Weighted Region Problem. In the Weighted Region Problem, the length of a path is defined as the sum of the weights of the subpaths within each region…
Minimum Exposure Motion Planning
Sarita de Berg, Joachim Gudmundsson, Peter Kramer +2
We investigate multiple fundamental variants of the classic coordinated motion planning (CMP) problem for unit square robots in the plane under the metric. In coordinated mot…
Instance-Optimal Imprecise Convex Hull
Sarita de Berg, Ivor van der Hoog, Eva Rotenberg +2
Imprecise measurements of a point set P = (p1, ..., pn) can be modelled by a family of regions F = (R1, ..., Rn), where each imprecise region Ri contains a unique point pi. A retri…
