Action Models with Postconditions

Abstract

This work proposes a extension of dynamic epistemic logic to work with assignment. The difference between this work and others works, such as [7], is the use of actions models, from DEL, to make Boolean assignments to the propositions, instead of creating new mechanisms to make the assignments. We extend the definition of action model by creating the postcondition property of each state of the model, making it possible to assign Boolean values to the propositions.
