Self-improving Algorithms for Convex Hulls
We describe an algorithm for computing planar convex hulls in the self-improving model: given a sequence I1, I2, . . . of planar n-point sets, the upper convex hull conv(I) of eac...

Multiple-antenna multiple-relay system with precoding for multiuser transmission
Multi-hop relaying will play a central role in next generation wireless systems. In this paper a novel relaying strategy that uses multiple-input multiple-output (MIMO) relays in ...

A New Algorithm for Finding Minimal Cycle-Breaking Sets of Turns in a Graph
We consider the problem of constructing a minimal cycle-breaking set of turns for a given undirected graph. This problem is important for deadlock-free wormhole routing in compute...
