Knowledge Compilation Properties of Tree-of-BDDs
We present a CNF to Tree-of-BDDs (ToB) compiler with complexity at most exponential in the tree width. We then present algorithms for interesting queries on ToB. Although some of ...

Computing Equilibria in Bimatrix Games by Parallel Support Enumeration
We consider the problem of computing all Nash equilibria in bimatrix games (i.e., nonzero-sum two-player noncooperative games). Computing all Nash equilibria for large bimatrix ga...

When Are Timed Automata Weakly Timed Bisimilar to Time Petri Nets?
In this paper4 , we compare Timed Automata (TA) and Time Petri Nets (TPN) with respect to weak timed bisimilarity. It is already known that the class of bounded TPNs is strictly in...

Introducing Communication in Dis-POMDPs with Locality of Interaction
The Networked Distributed POMDPs (ND-POMDPs) can model multiagent systems in uncertain domains and has begun to scale-up the number of agents. However, prior work in ND-POMDPs has ...

Ground Reducibility is EXPTIME-Complete
Abstract. We prove that ground reducibility is EXPTIME-complete in the general case. EXPTIME-hardness is proved by encoding the emptiness problem for the intersection of recognizab...
