Monochromatic geometric k-factors for bicolored point sets with auxiliary points
(2014)
Given a bicolored point set S, it is not always possible to construct a monochromatic geometric planar k-factor of S. We consider the problem of finding such a k-factor of S by using auxiliary points. Two types are considered: ...

Stabbing segments with rectilinear objects
(Elsevier, 2017)
Given a set S of n line segments in the plane, we say that a region R R2 is a stabber for S if R contains exactly one endpoint of each segment of S. In this paper we provide optimal or near-optimal algorithms for ...
