Minimum-Weight Steiner Triangulation of Convex Polygons Requires Interior Steiner Points

David Eppstein, Zahra Hadizadeh

We construct a convex polygon for which the minimum-weight Steiner triangulation requires an interior Steiner point. This provides a counterexample to a 1994 conjecture of Eppstein…

Tangent Spheres and Integer Distances

David Eppstein

The Erdős-Anning theorem states that any point set for which all distances are integers, in a Euclidean space of any dimension, must be either finite or collinear. We prove the sam…

Entropy-Bounded Computational Geometry Made Easier and Sensitive to Sortedness

David Eppstein, Michael T. Goodrich, Abraham M. Illickan +1

We study entropy-bounded computational geometry, that is, geometric algorithms whose running times depend on a given measure of the input entropy. Specifically, we introduce a meas…

Visualizing Treewidth

Alvin Chiu, Thomas Depian, David Eppstein +2

A witness drawing of a graph is a visualization that clearly shows a given property of a graph. We study and implement various drawing paradigms for witness drawings to clearly sho…

Better Late than Never: the Complexity of Arrangements of Polyhedra

Boris Aronov, Sang Won Bae, Sergio Cabello +4

Let be the subdivision of induced by convex polyhedra having facets in total. We prove that has combinatorial complexity $O(m^{\l…

Drawing Planar Graphs and 1-Planar Graphs Using Cubic Bézier Curves with Bounded Curvature

David Eppstein, Michael T. Goodrich, Abraham M. Illickan

We study algorithms for drawing planar graphs and 1-planar graphs using cubic Bézier curves with bounded curvature. We show that any n-vertex 1-planar graph has a 1-planar RAC draw…
