Colored ray configurations
Ruy Fabila-Monroy, Alfredo García, Ferran Hurtado +6
We study the cyclic color sequences induced at infinity by colored rays with apices being a given balanced finite bichromatic point set. We first study the case in which the rays a…
On contractible edges in convex decompositions
Ferran Hurtado, Eduardo Rivera-Campo
Let be a convex decomposition of a set of points in general position in the plane. If consists of more than one polygon, then either contains a deletable…
Balanced partitions of 3-colored geometric sets in the plane
Sergey Bereg, Matias Korman, Rodrigo I. Silveira +6
Let be a finite set of geometric objects partitioned into classes or \emph{colors}. A subset is said to be \emph{balanced} if contains the same amount of e…
Geometric Biplane Graphs II: Graph Augmentation
Alfredo García, Ferran Hurtado, Matias Korman +5
We study biplane graphs drawn on a finite point set in the plane in general position. This is the family of geometric graphs whose vertex set is and which can be decomposed…
Geometric Biplane Graphs I: Maximal Graphs
Alfredo García, Ferran Hurtado, Matias Korman +5
We study biplane graphs drawn on a finite planar point set in general position. This is the family of geometric graphs whose vertex set is and can be decomposed into two pl…
Colored Spanning Graphs for Set Visualization
Ferran Hurtado, Matias Korman, Marc van Kreveld +6
We study an algorithmic problem that is motivated by ink minimization for sparse set visualizations. Our input is a set of points in the plane which are either blue, red, or purple…
