We present fully polynomial-time (deterministic or randomised) approximation schemes for Holant problems, defined by a non-negative constraint functio......

It was recently found that there are very close connections between the existence of additive spanners (sub-graphs where all distances are preserved u......

We present a unified (randomized) polynomial-time approximation scheme (PTAS) for the prize collecting traveling salesman problem (PCTSP) and the priz......

Often in a scheduling problem, there is uncertainty about the jobs to be processed. The issue of uncertainty regarding the machines has been much less......

This article presents a randomized (Las Vegas) distributed algorithm that constructs a minimum spanning tree (MST) in weighted networks with optimal (......

The complexity of distributed edge coloring depends heavily on the palette size as a function of the maximum degree Delta. In this article, we explore......

We study the problem of testing whether an unknown n-variable Boolean function is a k-junta in the distribution-free property testing model, where the......

We introduce a weighted version of the ranking algorithm by Karp et al. (STOC 1990), and we prove a competitive ratio of 0.6534 for the vertex-weighte......

We present a new scaling algorithm for maximum (or minimum) weight perfect matching on general, edge weighted graphs. Our algorithm runs in O(m root n......

We consider the problem of online scheduling of jobs on unrelated machines with dynamic speed scaling to minimize the sum of energy and weighted flow-......

We consider the Traveling Salesman Problem with Neighborhoods (TSPN) in doubling metrics. The goal is to find the shortest tour that visits each of a ......

We consider a natural generalization of the classical multiple knapsack problem in which instead of packing single items we are packing groups of item......

We study the online submodular maximization problem with free disposal under a matroid constraint. Elements from some ground set arrive one by one in ......

We study the problem of two-dimensional orthogonal range counting with additive error. Given a set P of n points drawn from an n x n grid and an error......

We prove the first non-trivial performance ratio strictly above 0.5 for the weighted Ranking algoritlun on the oblivious matching problem where nodes ......
