Epistemic reasoning explained with the tool Hintikka's World

11.06.2019, 11:00
Pavillon des Jardins
Francois Schwarzentruber (ENS Rennes)

In this talk, we will present Dynamic Epistemic Logic which provides a framework to model epistemic situations their evolution in time. The framework is sufficiently expressive to capture public actions (e.g. broadcast of a message) but also private and semi-private actions (e.g. private messages). The framework will be explained via a software, called Hintikka’s world. We will discuss about symbolic models, which allows to represent situations with a high number of possible worlds. We then address model checking and the satisfiability problem that are standard decision problems for verifying multi-agent systems. We address epistemic planning which is undecidable in general. We will pinpoint restrictions over actions (e.g. only public actions, etc.) for which epistemic planning is decidable.
