K-transversals of Parallel Convex Sets
R d can be divided into a union of parallel d k ats of the form x g x g xk gk where the gi are constant Let C be a family of parallel d k dimensional convex sets meaning that each is contained in one of the above parallel d k ats We give a parameterization of the set of k ats in R such that the set of k ats which intersect in a point any set c C is convex Parameterizing the lines in R through h...
متن کاملNotes on Convex Transversals
In this paper, we prove the problem of stabbing a set of disjoint bends by a convex stabber to be NP-hard. We also consider the optimization version of the convex stabber problem and prove this problem to be APX-hard for sets of line segments.
متن کاملCommon Transversals
Given t families, each family consisting of s finite sets, we show that if the families “separate points" in a natural way, and if the union of all the sets in all the families contains more than (s+1)t st 1 1 elements, then a common transversal of the t families exists. In case each family is a covering family, the bound is st st 1. Both of these bounds are best possible. This work extends rec...
متن کاملConvex Transversals
We answer the question initially posed by Arik Tamir at the Fourth NYU Computational Geometry Day (March, 1987): “Given a collection of compact sets, can one decide in polynomial time whether there exists a convex body whose boundary intersects every set in the collection?” We prove that when the sets are segments in the plane, deciding existence of the convex stabber is NP-hard. The problem re...
متن کاملOn the Milner-shelah Condition for Transversals
2. An important concept will be that of a component of a family 2F. Consider the equivalence relation on / generated by the relation R defined by: i'RV'o Fv n Fr T* 0 . Let /* be any equivalence class. Then &* = is, by definition, a component of $F. If Fv and Fv> are in different components, then jp., n Fv> = 0 . This means that 0? has a transversal if and only if every component of ...
