Optimal approximations of the frequency moments of data streams
We give a 1-pass ~O(m1-2/k )-space algorithm for computing the k-th frequency moment of a data stream for any real k > 2. Together with the lower bounds of [1, 2, 4], this reso...

Routing complexity of faulty networks
One of the fundamental problems in distributed computing is how to efficiently perform routing in a faulty network in which each link fails with some probability. This paper inves...

Covering a Set of Points with a Minimum Number of Lines
We consider the minimum line covering problem: given a set S of n points in the plane, we want to find the smallest number l of straight lines needed to cover all n points in S. W...

Computing the Greedy Spanner in Near-Quadratic Time
It is well-known that the greedy algorithm produces high quality spanners and therefore is used in several applications. However, for points in d-dimensional Euclidean space, the g...

Reliability-Based Decoding for Convolutional Tail-Biting Codes
— In this work, we proposed a reliability-based enhancement for the Viterbi and the optimal decoding of the convolutional tailbiting codes (CTBC) from the observations that the d...
