Constrained Epistemic Action Modal Logic

In this paper, the constrained epistemic default logic and action model logic was combined to model the dynamic cognitive update process by introducing a cognitive operator. The description of the logic framework was given in this study, and the related theorems were proved to show the interpretation of the constrained epistemic action model logic. As constrained epistemic default logic restricts the current possible epistemic state and action model logic can describe epistemic actions, the new proposed logic can better portray the cognitive operations and the restriction of the corresponding accessibility relations.
