Lower Bounds on Communication Loads and Optimal Placements in Torus Networks
Fully-populated tori, where every node has a processor attached, do not scale well since load on edges increases superlinearly with network size under heavy communication, resulti...

Approximation Bounds for a General Class of Precedence Constrained Parallel Machine Scheduling Problems
Abstract. A well studied and difficult class of scheduling problems concerns parallel machines and precedence constraints. In order to model more realistic situations, we consider ...

Partitioning Posets
Given a poset P = (X, ), a partition X1, . . . , Xk of X is called an ordered partition of P if, whenever x Xi and y Xj with x y, then i j. In this paper, we show that for ever...

QoM and lifetime-constrained random deployment of sensor networks for minimum energy consumption
— We consider the problem of energy efficient random deployment of sensor network. Our goal is to find the sensor node density, or alternatively, the energy resource density at e...

A parallel repetition theorem
We show that a parallel repetition of any two-prover one-round proof system (MIP(2, 1)) decreases the probability of error at an exponential rate. No constructive bound was previou...
