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…

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…

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…

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…

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…

Sparse geometric graphs with small dilation

Boris Aronov, Mark de Berg, Otfried Cheong +4

Given a set S of n points in R^D, and an integer k such that 0 <= k < n, we show that a geometric graph with vertex set S, at most n - 1 + k edges, maximum degree five, and dilatio…
