On Frequency LTL in Probabilistic Systems
Vojtěch Forejt, Jan Krčál
We study frequency linear-time temporal logic (fLTL) which extends the linear-time temporal logic (LTL) with a path operator expressing that on a path, certain formula holds…
Dealing with Zero Density Using Piecewise Phase-type Approximation
Ľuboš Korenčiak, Jan Krčál, Vojtěch Řehák
Every probability distribution can be approximated up to a given precision by a phase-type distribution, i.e. a distribution encoded by a continuous time Markov chain (CTMC). Howev…
Probabilistic Bisimulation: Naturally on Distributions
Holger Hermanns, Jan Krčál, Jan Křetínský
In contrast to the usual understanding of probabilistic systems as stochastic processes, recently these systems have also been regarded as transformers of probabilities. In this pa…
Probabilistic Bisimulations for PCTL Model Checking of Interval MDPs
Vahid Hashemi, Hassan Hatefi, Jan Krčál
Verification of PCTL properties of MDPs with convex uncertainties has been investigated recently by Puggelli et al. However, model checking algorithms typically suffer from state s…
