On the Stability of Minimum-Weight Perfect Matching on the Line
Mark de Berg, Ulrike Schmidt-Kraepelin, Andree-Ovidiu Stef
Computing a minimum-weight perfect matching for a point set in Euclidean space is a classic geometric optimization problem. We consider the problem in a dynamic setting, where…
Truthful Budget Aggregation: Beyond Moving-Phantom Mechanisms
Mark de Berg, Rupert Freeman, Ulrike Schmidt-Kraepelin +1
We study a budget-aggregation setting in which a number of voters report their ideal distribution of a budget over a set of alternatives, and a mechanism aggregates these reports i…
A Clique-Based Separator for Intersection Graphs of Geodesic Disks in
Boris Aronov, Mark de Berg, Leonidas Theocharous
Let be a (well-behaved) shortest-path metric defined on a path-connected subset of and let be a set of geodesic disks with respe…
A Coreset for Approximate Furthest-Neighbor Queries in a Simple Polygon
Mark de Berg, Leonidas Theocharous
Let be a simple polygon with vertices and let be a set of points inside . We prove that there exists, for any , a set $\mathca…
Finding Diverse Minimum s-t Cuts
Mark de Berg, Andrés López Martínez, Frits Spieksma
Recently, many studies have been devoted to finding diverse solutions in classical combinatorial problems, such as Vertex Cover (Baste et al., IJCAI'20), Matching (Fomin et al., IS…
-Center Clustering with Outliers in the MPC and Streaming Model
Mark de Berg, Leyla Biabani, Morteza Monemizadeh
Given a point set of size in a metric space of doubling dimension and two parameters and , the -center problem with out…
Computing Smallest Convex Intersecting Polygons
Antonios Antoniadis, Mark de Berg, Sándor Kisfaludi-Bak +1
A polygon C is an intersecting polygon for a set O of objects in the plane if C intersects each object in O, where the polygon includes its interior. We study the problem of comput…
Partitioning axis-parallel lines in 3D
Boris Aronov, Abdul Basit, Mark de Berg +1
Let be a set of axis-parallel lines in . We are are interested in partitions of by a set of three planes such that each open cell in the ar…
Stable Approximation Algorithms for the Dynamic Broadcast Range-Assignment Problem
Mark de Berg, Arpan Sadhukhan, Frits Spieksma
Let be a set of points in , where each point has an associated transmission range . The range assignment induces a directed communication graph…
Euclidean TSP in Narrow Strips
Henk Alkema, Mark de Berg, Remco van der Hofstad +1
We investigate how the complexity of Euclidean TSP for point sets inside the strip depends on the strip width . We obtain two main results. F…
An ETH-Tight Exact Algorithm for Euclidean TSP
Mark de Berg, Hans L. Bodlaender, Sándor Kisfaludi-Bak +1
We study exact algorithms for Euclidean TSP in . In the early 1990s algorithms with running time were presented for the planar case, and some years…
Minimum Perimeter-Sum Partitions in the Plane
Mikkel Abrahamsen, Mark de Berg, Kevin Buchin +2
Let be a set of points in the plane. We consider the problem of partitioning into two subsets and such that the sum of the perimeters of an…
Fully-Dynamic and Kinetic Conflict-Free Coloring of Intervals with Respect to Points
Mark de Berg, Tim Leijsen, André van Renssen +3
We introduce the fully-dynamic conflict-free coloring problem for a set of intervals in with respect to points, where the goal is to maintain a conflict-free col…
Removing Depth-Order Cycles Among Triangles: An Efficient Algorithm Generating Triangular Fragments
Mark de Berg
More than 25 years ago Chazelle~\emph{et al.} (FOCS 1991) studied the following question: Is it possible to cut any set of lines in into a subquadratic number of f…
Shortcuts for the Circle
Sang Won Bae, Mark de Berg, Otfried Cheong +2
Let be the unit circle in . We can view as a plane graph whose vertices are all the points on , and the distance between any two points on is the lengt…
Independent Set Reconfiguration Thresholds of Hereditary Graph Classes
Mark de Berg, Bart M. P. Jansen, Debankur Mukherjee
Traditionally, reconfiguration problems ask the question whether a given solution of an optimization problem can be transformed to a target solution in a sequence of small steps th…
Distance-Sensitive Planar Point Location
Boris Aronov, Mark de Berg, David Eppstein +2
Let be a connected planar polygonal subdivision with edges that we want to preprocess for point-location queries, and where we are given the probability tha…

We show that there exists a geodesic spanner with almost linear number of edges.
Treemaps with Bounded Aspect Ratio
Mark de Berg, Bettina Speckmann, Vincent van der Weele
Treemaps are a popular technique to visualize hierarchical data. The input is a weighted tree $\tree$ where the weight of each node is the sum of the weights of its children. A tre…
