Farthest color Voronoi diagrams: complexity and algorithms

I Mantas, E Papadopoulou, V Sacristán… - … American symposium on …, 2020 - Springer
The farthest-color Voronoi diagram (FCVD) is a farthest-site Voronoi structure defined on a
family PP of m point-clusters in the plane, where the total number of points is n. The FCVD …

Discrete and mixed two-center problems for line segments

S Maji, S Sadhu - Information Processing Letters, 2024 - Elsevier
Given a set of n non-intersecting line segments L and a set Q of m points in R 2; we present
algorithms of the discrete two-center problem for (i) covering,(ii) stabbing and (iii) hitting the …

Randomized incremental construction for the Hausdorff Voronoi diagram revisited and extended

E Arseneva, E Papadopoulou - Journal of Combinatorial Optimization, 2019 - Springer
Abstract The Hausdorff Voronoi diagram of clusters of points in the plane is a generalization
of Voronoi diagrams based on the Hausdorff distance function. Its combinatorial complexity …

Capturing the Shape of a Point Set with a Line Segment

N van Beusekom, M van Kreveld, M van Mulken… - arxiv preprint arxiv …, 2024 - arxiv.org
Detecting location-correlated groups in point sets is an important task in a wide variety of
applications areas. In addition to merely detecting such groups, the group's shape carries …

Searching edges in the overlap of two plane graphs

J Iacono, E Khramtcova, S Langerman - Workshop on Algorithms and …, 2017 - Springer
Consider a pair of plane straight-line graphs whose edges are colored red and blue,
respectively, and let n be the total complexity of both graphs. We present a O (nn)-time O (n) …

On covering segments with unit intervals

D Bergren, E Eiben, R Ganian, I Kanj - SIAM Journal on Discrete Mathematics, 2022 - SIAM
We study the problem of covering a set of segments on a line with the minimum number of
unit-length intervals, where an interval covers a segment if at least one of the two endpoints …

The farthest color Voronoi diagram in the plane

I Mantas, E Papadopoulou, RI Silveira, Z Wang - 2024 - researchsquare.com
The farthest-color Voronoi diagram (FCVD) is defined on a set of $ n $ points in the plane,
each of which is labeled with one of $ m $ colors. The colored points can be seen as a family …

Stabbing segments with rectilinear objects

M Claverol, D Garijo, M Korman, C Seara… - Applied Mathematics and …, 2017 - Elsevier
Given a set S of n line segments in the plane, we say that a region R⊆ R 2 is a stabber for S
if R contains exactly one endpoint of each segment of S. In this paper we provide optimal or …

Stabbing balls with line segments and polygonal paths

A Neuhaus, D Rohde - arxiv preprint arxiv:2212.01458, 2022 - arxiv.org
We study the problem of ordered stabbing of $ n $ balls (of arbitrary and possibly different
radii, no ball contained in another) in $\mathbb {R}^ d $, $ d\geq 3$, with either a directed …

Let S be a set of n disjoint segments in the plane that correspond to edges of the Delaunay
triangulation of some fixed point set. Our goal is to compute all the combinatorially different …
