Hitting Geometric Range Spaces using a Few Points
(2018-02-15)
A range space (P, S) consists of a set P of n elements and a collection S = {S1,...,Sm} of subsets of P , referred to as ranges. A hitting set for this range space refers to a subset H of P such that every Si in S contains ...
Variants and Generalization of Some Classical Problems in Combinatorial Geometry
(2018-02-18)
In this thesis we consider extensions and generalizations of some classical problems
in Combinatorial Geometry. Our work is an offshoot of four classical problems in
Combinatorial Geometry. A fundamental assumption in these ...
