A real-time computer system is a system that must perform its functions within specified time bounds. These systems are generally characterized by complex interactions with the en...
We provide a method whereby, given mode and (upper approximation) type information, we can detect procedures and goals that can be guaranteed to not fail (i.e., to produce at leas...
We give a practical and provably good Monte Carlo algorithm for approximating center points. Let P be a set of n points in IRd . A point c ∈ IRd is a β-center point of P if eve...

We establish the complexity of decision problems associated with the nonmonotonic modal logic S4. We prove that the problem of existence of an S4-expansion for a given set A of pr...
Autonomous agents working in multi-agent environments may need to cooperate in order to ful ll tasks. Given a set of agents and a set of tasks which they have to satisfy, we consi...
