Randomized algorithms for tracking distributed count, frequencies, and ranks
We show that randomization can lead to significant improvements for a few fundamental problems in distributed tracking. Our basis is the count-tracking problem, where there are k...

Radix Sorting with No Extra Space
It is well known that n integers in the range [1, nc ] can be sorted in O(n) time in the RAM model using radix sorting. More generally, integers in any range [1, U] can be sorted i...
