Lower Bounds for Smith's Rule in Stochastic Machine Scheduling
We consider the problem to minimize the weighted sum of completion times in nonpreemptive parallel machine scheduling. In a landmark paper from 1986, Kawaguchi and Kyan [5] showed ...

Optimal arrangement of data in a tree directory
We define the decision problem data arrangement, which involves arranging the vertices of a graph G at the leaves of a d-ary tree so that a weighted sum of the distances between p...

Scheduling of Multi-Antenna Broadcast Systems with Heterogeneous Users
— We consider a two transmit antenna broadcast system with heterogeneous users, and tackle the problem of maximizing a weighted sum rate. We establish a novel upper bound for the...
