Entailment of Atomic Set Constraints is PSPACE-Complete
The complexity of set constraints has been extensively studied over the last years and was often found quite high. At the lower end of expressiveness, there are atomic set constra...

Local mode dependent decentralized control of uncertain Markovian jump large-scale systems
Abstract— This paper is concerned with the robust stabilization of a class of stochastic large-scale systems. The uncertainties satisfy integral quadratic constraints. The random...

How to Play Unique Games Using Embeddings
In this paper we present a new approximation algorithm for Unique Games. For a Unique Game with n vertices and k states (labels), if a (1 − ε) fraction of all constraints is sa...

Power-Time Tradeoff in Test Scheduling for SoCs
We present a test scheduling methodology for core-based system-on-chips that allows tradeoff between system power dissipation and overall test time. The basic strategy is to use t...

Word Equations over Graph Products
For monoids that satisfy a weak cancellation condition, it is shown that the decidability of the existential theory of word equations is preserved under graph products. Furthermore...
