Distributed Selection in Time with Messages

Piotr Berman, Junichiro Fukuyama

We consider the selection problem on a completely connected network of processors with no shared memory. Each processor initially holds a given numeric item of bits allowed…

Tolerant Testers of Image Properties

Piotr Berman, Meiram Murzabulatov, Sofya Raskhodnikova

We initiate a systematic study of tolerant testers of image properties or, equivalently, algorithms that approximate the distance from a given image to the desired property (that i…

Approximating the Online Set Multicover Problems Via Randomized Winnowing

Piotr Berman, Bhaskar DasGupta

In this paper, we consider the weighted online set k-multicover problem. In this problem, we have a universe V of elements, a family S of subsets of V with a positive real cost for…

On Approximating Four Covering and Packing Problems

Mary Ashley, Tanya Berger-Wolf, Piotr Berman +3

In this paper, we consider approximability issues of the following four problems: triangle packing, full sibling reconstruction, maximum profit coverage and 2-coverage. All of them…

Steiner Transitive-Closure Spanners of d-Dimensional Posets

Piotr Berman, Arnab Bhattacharyya, Elena Grigorescu +3

Given a directed graph G and an integer k >= 1, a k-transitive-closure-spanner (k-TCspanner) of G is a directed graph H that has (1) the same transitive-closure as G and (2) diamet…
