Walrasian Equilibrium: Hardness, Approximations and Tractable Instances
We study the complexity issues for Walrasian equilibrium in a special case of combinatorial auction, called single-minded auction, in which every participant is interested in only ...

Weakly Hard Real-time Constraints on Controller Area Network
For priority based buses such as CAN, worst case response time analysis is able to determine whether messages always meet their deadlines. This can include system models with boun...

Breaking up is hard to do: an investigation of decomposition for assume-guarantee reasoning
Finite-state verification techniques are often hampered by the stateexplosion problem. One proposed approach for addressing this problem is assume-guarantee reasoning. Using rece...

How Hard Is Bribery in Elections?
We study the complexity of influencing elections through bribery: How computationally complex is it for an external actor to determine whether by paying certain voters to change t...
