Randomized Protocols for Low Congestion Circuit Routing in Multistage Interconnection Networks
In this paper we study randomized algorithms for circuit switching on multistage networks related to the butterfly. We devise algorithms that route messages by constructing circu...

Low-Dimensional Faces of Random 0/1-Polytopes
Let P be a random 0/1-polytope in d with n(d) vertices, and denote by k(P) the k-face density of P, i.e., the quotient of the number of k-dimensional faces of P and `n(d) k+1

Randomness, lowness and degrees
We say that A LR B if every B-random number is A-random. Intuitively this means that if oracle A can identify some patterns on some real , oracle B can also find patterns on . In o...

Informative sensing of natural images
The theory of compressed sensing tells a dramatic story that sparse signals can be reconstructed near-perfectly from a small number of random measurements. However, recent work ha...
