  • Informatics Colloquium 23.4. What is the best timeout?

    Informatics Colloquium 23. 4. 2019, 14:00 lecture hall D2 RNDr. Vojtěch Řehák, Ph.D., FI MU What is the best timeout? Abstract: We all have some experience with deadlines, and we know how hard it is to deliver results in time, especially when some obstacles with an uncertain solving time may occur. In this talk, we deal with formalisms suitable for modeling and analysis of such systems, i.e., reflecting both timeouts and actions taking stochastic continuous time. We show how this kind of stochastic timed systems can be modeled and what properties can be computed for such models. On surprisingly small examples we also demonstrate some fundamental limits of such models. Then we will consider that some parts of the model are unknown and we take them as parameters that we would like to synthesize automatically. Finally, we will present results allowing for the synthesis of (epsilon)-optimal timeouts in such systems.
