Voronoi diagrams for a moderate-sized point-set in a simple polygon

E Oh, HK Ahn - Discrete & Computational Geometry, 2020 - Springer
Given a set of sites in a simple polygon, a geodesic Voronoi diagram of the sites partitions
the polygon into regions based on distances to sites under the geodesic metric. We present …

An optimal deterministic algorithm for geodesic farthest-point Voronoi diagrams in simple polygons

H Wang - Discrete & Computational Geometry, 2023 - Springer
Given in the plane a set S of m point sites in a simple polygon P of n vertices, we consider
the problem of computing the geodesic farthest-point Voronoi diagram for S in P. It is known …

Optimal algorithm for geodesic nearest-point Voronoi diagrams in simple polygons

E Oh - Proceedings of the Thirtieth Annual ACM-SIAM …, 2019 - SIAM
Given a set of m point sites in a simple polygon, the geodesic nearest-point Voronoi diagram
of the sites partitions the polygon into m Voronoi cells, one cell per site, such that every point …

[HTML][HTML] Computing the geodesic centers of a polygonal domain

SW Bae, M Korman, Y Okamoto - Computational Geometry, 2019 - Elsevier
We present an algorithm that computes the geodesic center of a given polygonal domain.
The running time of our algorithm is O (n 12+ ϵ) for any ϵ> 0, where n is the number of …

[HTML][HTML] Computing a geodesic two-center of points in a simple polygon

E Oh, SW Bae, HK Ahn - Computational Geometry, 2019 - Elsevier
Given a simple polygon P with n vertices and a set Q of m points in P, we consider the
geodesic k-center problem where we want to find k points, called centers, in P to minimize …

[HTML][HTML] The geodesic 2-center problem in a simple polygon

E Oh, JL De Carufel, HK Ahn - Computational Geometry, 2018 - Elsevier
In the geodesic 2-center problem in a simple polygon with n vertices, we find a set S of two
points in the polygon that minimizes the maximum geodesic distance from any point of the …

Optimal algorithm for geodesic farthest-point Voronoi diagrams

L Barba - 35th International Symposium on …, 2019 - research-collection.ethz.ch
Let P be a simple polygon with n vertices. For any two points in P, the geodesic distance
between them is the length of the shortest path that connects them among all paths …

Clustering in Polygonal Domains

M de Berg, L Biabani, M Monemizadeh… - … on Algorithms and …, 2023 - drops.dagstuhl.de
We study various clustering problems for a set D of n points in a polygonal domain P under
the geodesic distance. We start by studying the discrete k-median problem for D in P. We …

On the geodesic centers of polygonal domains

H Wang - Journal of Computational Geometry, 2018 - jocg.org
In this paper, we study the problem of computing Euclidean geodesic centers of a polygonal
domain $ P $ with a total of $ n $ vertices. We discover many interesting observations. We …
