Coloring circle arrangements: New -chromatic planar graphs

Man-Kwun Chiu, Stefan Felsner, Manfred Scheucher +3

Felsner, Hurtado, Noy and Streinu (2000) conjectured that arrangement graphs of simple great-circle arrangements have chromatic number at most . Motivated by this conjecture, we…

Snipperclips: Cutting Tools into Desired Polygons using Themselves

Zachary Abel, Hugo Akitaya, Man-Kwun Chiu +7

We study Snipperclips, a computer puzzle game whose objective is to create a target shape with two tools. The tools start as constant-complexity shapes, and each tool can snip (i.e…

Recognizing embedded caterpillars with weak unit disk contact representations is NP-hard

Man-Kwun Chiu, Jonas Cleve, Martin Nöllenburg

Weak unit disk contact graphs are graphs that admit a representation of the nodes as a collection of internally disjoint unit disks whose boundaries touch if there is an edge betwe…

Distance bounds for high dimensional consistent digital rays and 2-D partially-consistent digital rays

Man-Kwun Chiu, Matias Korman, Martin Suderland +1

We consider the problem of digitalizing Euclidean segments. Specifically, we look for a constructive method to connect any two points in . The construction must be {\…

Computational Complexity of the -Ham-Sandwich Problem

Man-Kwun Chiu, Aruni Choudhary, Wolfgang Mulzer

The classic Ham-Sandwich theorem states that for any measurable sets in , there is a hyperplane that bisects them simultaneously. An extension by Bárány, Hubard,…

A Generalization of Self-Improving Algorithms

Siu-Wing Cheng, Man-Kwun Chiu, Kai Jin +1

Ailon et al. [SICOMP'11] proposed self-improving algorithms for sorting and Delaunay triangulation (DT) when the input instances follow some unknown \emph{product…
