An Almost Linear Time 2.8334-Approximation Algorithm for the Disc Covering Problem
The disc covering problem asks to cover a set of points on the plane with a minimum number of fix-sized discs. We develop an O(n(log n)2 (log log n)2 ) deterministic time 2.8334-a...

An adjustable linear time parallel algorithm for maximum weight bipartite matching
We present a parallel algorithm for finding a maximum weight matching in general bipartite graphs with an adjustable time complexity of O(n ) using O(nmax(2,4+)) processing

A Randomized Time-Work Optimal Parallel Algorithm for Finding a Minimum Spanning Forest
We present a randomized algorithm to nd a minimum spanning forest (MSF) in an undirected graph. With high probability, the algorithm runs in logarithmic time and linear work on an...
