Efficient computation of minimum-area rectilinear convex hull under rotation and generalizations
Carlos Alegría-Galicia, David Orden, Carlos Seara +1
Let be a set of points in the plane. We compute the value of for which the rectilinear convex hull of , denoted by , has minimum (or max…
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…
Antimagic Labelings of Caterpillars
Antoni Lozano, Mercè Mora, Carlos Seara
A -antimagic labeling of a graph is an injection from to such that all vertex sums are pairwise distinct, where the vertex sum at vertex …
-covering red and blue points in the plane
Bernardo M. Ábrego, Silvia Fernández-Merchant, Mikio Kano +4
We say that a finite set of red and blue points in the plane in general position can be -covered if the set can be partitioned into subsets of size , with points of…
Stabbing segments with rectilinear objects
Mercè Claverol, Delia Garijo, Matias Korman +2
Given a set of line segments in the plane, we say that a region is a {\em stabber} for if contains exactly one endpoin…
