Dynamic Epistemic Logic and Epistemic Planning
half day tutorial at KR 2020
Rhodes, 12-18 Sep. 2020
Lecturer: Andreas Herzig
The generation of plans for multiple agents goes beyond classical planning
in that it typically involves reasoning about the agents' knowledge,
including higher-order knowledge (such as knowledge about other agents' knowledge).
This requires a reexamination of the relevant concepts and models.
While the concepts of initial situation and goal can be adequately described
in epistemic logic, the concept of an action description
calls for a combination of epistemic logic and a logic of action.
Dynamic epistemic logic provides a powerful framework for such a combination.
It however also comes with some conceptual and computational difficulties.
I finally argue for a simple epistemic logic that is grounded in
what the agents observe.
