Center node: "probabilistic bisimulations for pctl model checking of interval mdps"
  Abstract: Verification of PCTL properties of MDPs with convex uncertai nties has been investigated recently by Puggelli et al. However, model checking algorithms typically suffer from state space explosion. In this paper, we address probabilistic bisimulation to reduc e the size of such an MDPs while preserving PCTL properties it satisfies. We discuss different interpre tations of uncertainty in the models which are studied in the literature and that result in two differen t definitions of bisimulations. We give algorithms to compute the quotients of these bisimulations in time polynomial in the size of the model and exponential in the uncertain branching. Finally, we show by a case study that large models in practice can have small branching and that a substantial state space reduction can be achieved by our approach.
