Inapproximability of Hypergraph Vertex Cover and Applications to Scheduling Problems
Assuming the Unique Games Conjecture (UGC), we show optimal inapproximability results for two classic scheduling problems. We obtain a hardness of 2 − ε for the problem of mini...

ATL with Strategy Contexts: Expressiveness and Model Checking
We study the alternating-time temporal logics ATL and ATL extended with strategy contexts: these make agents commit to their strategies during the evaluation of formulas, contrary...

Automated Systematic Testing of Open Distributed Programs
We present an algorithm for automatic testing of distributed programs, such as Unix processes with inter-process communication and Web services. Specifically, we assume that a prog...
