Linear-Size Universal Point Sets for One-Bend Drawings [PDF]

open access: yes, 2015
For every integer $n ge 4$, we construct a planar point set $S_n$ of size $6n-10$ such that every $n$-vertex planar graph $G$ admits a plane embedding in which the vertices are mapped to points in $S_n$, and every edge is either a line segment or a ...

On morphs of 1-plane graphs [PDF]

open access: yes, 2022
Morphing geometric graphs is a classical problem in graph theory and computational geometry with seminal results established by Cairns in 1944 [Amer. Math. Monthly, 51] and by Thomassen in 1983 [J. of Comb. Theor., Series B, 34].

Mixed Map Labeling

open access: yesJournal of Spatial Information Science, 2016
Point feature map labeling is a geometric visualization problem, in which a set of input points must be labeled with a set of disjoint rectangles (the bounding boxes of the label texts).

Quantum Computation in Computational Geometry

open access: yesInterdisciplinary Information Sciences, 2002
Summary: We discuss applications of quantum computation to geometric data processing. These applications include problems on convex hulls, minimum enclosing balls, linear programming, and intersection problems. Technically, we apply the well-known algorithm of \textit{L. K. Grover} [Proc. 28th annual ACM symposium 1996, 212--219 (1996; Zbl 0922.68044)]

Multi-Colored Spanning Graphs [PDF]

open access: yes, 2016
We study a problem proposed by Hurtado et al. [10] motivated by sparse set visualization. Given n points in the plane, each labeled with one or more primary colors, a colored spanning graph (CSG) is a graph such that for each primary color, the vertices ...

A Refined Definition for Groups of Moving Entities and its Computation [PDF]

open access: yes, 2016
One of the important tasks in the analysis of spatio-temporal data collected from moving entities is to find a group: a set of entities that travel together for a sufficiently long period of time. Buchin et al.

Computational geometry and discrete computations [PDF]

open access: yes, 1996
In this paper we describe some problems arising in practical implementation of algorithms from computational geometry. Going to robust algorithms needs to solve issues such as rounding errors and degeneracies. Most of the problems are closely related to the incompatibility between on one side algorithms designed for continuous data and on the other ...

Single-player and two-player buttons & scissors games [PDF]

open access: yes, 2016
We study the computational complexity of the Buttons & Scissors game and obtain sharp thresholds with respect to several parameters. Specifically we show that the game is NP-complete for C = 2 colors but polytime solvable for C = 1. Similarly the game is
