The existential theory of the reals as a complexity class: A compendium

M Schaefer, J Cardinal, T Miltzow - arxiv preprint arxiv:2407.18006, 2024 - arxiv.org
We survey the complexity class $\exists\mathbb {R} $, which captures the complexity of
deciding the existential theory of the reals. The class $\exists\mathbb {R} $ has roots in two …

On the Complexity of Lombardi Graph Drawing

P Jungeblut - International Symposium on Graph Drawing and …, 2023 - Springer
In a Lombardi drawing of a graph the vertices are drawn as points and the edges are drawn
as circular arcs connecting their respective endpoints. Additionally, all vertices have perfect …

The complexity of drawing a graph in a polygonal region

A Lubiw, T Miltzow, D Mondal - Journal of Graph Algorithms …, 2022 - jgaa-v4.cs.brown.edu
We prove that the following problem is complete for the existential theory of the reals: Given
a planar graph and a polygonal region, with some vertices of the graph assigned to points …

The parametrized complexity of the segment number

S Cornelsen, G Da Lozzo, L Grilli, S Gupta… - … Symposium on Graph …, 2023 - Springer
Given a straight-line drawing of a graph, a segment is a maximal set of edges that form a line
segment. Given a planar graph G, the segment number of G is the minimum number of …

The segment number: algorithms and universal lower bounds for some classes of planar graphs

I Goeßmann, J Klawitter, B Klemz, F Klesen… - … Workshop on Graph …, 2022 - Springer
The of a planar graph G is the smallest number of line segments needed for a planar straight-
line drawing of G. Dujmović, Eppstein, Suderman, and Wood [CGTA'07] introduced this …

[PDF][PDF] Capturing the Computational Complexity of Geometric Problems by the First-Order Theory of the Reals

P Jungeblut - 2024 - scholar.archive.org
In this thesis, we explore a young branch of computational complexity that deals with
problems whose solutions consist of real numbers subject to a given set of polynomial …

The complexity of drawing graphs on few lines and few planes

S Chaplick, K Fleszar, F Lipp, A Ravsky… - arxiv preprint arxiv …, 2016 - arxiv.org
It is well known that any graph admits a crossing-free straight-line drawing in $\mathbb {R}^
3$ and that any planar graph admits the same even in $\mathbb {R}^ 2$. For a graph $ G …

Arrangement Graphs and Intersection Graphs of Curves

U kant Sahoo - 2022 - dspace.isical.ac.in
An arrangement of a set of non-self-intersecting curves is their embedding in the Euclidean
plane such that at each intersection point the curves involved cross each other …

Geometric Representations of Graphs: Theory and Application

F Klesen - 2025 - opus.bibliothek.uni-wuerzburg.de
Graph Drawing is a field of research that has application in any field of science that needs to
visualize binary relations. This thesis covers various problems arising when drawing graphs …

Pseudoline arrangement graphs: degree sequences and eccentricities

S Das, SB Rao - arxiv preprint arxiv:2103.02283, 2021 - arxiv.org
A pseudoline arrangement graph is a planar graph induced by an embedding of a (simple)
pseudoline arrangement. We study the corresponding graph realization problem and …
