Reiter's original definition of default logic allows for the application of a default that contradicts a previously applied one. We call this condition failure. The possibility of generating failures has been in the past considered as a semantical problem, and variants have been proposed to solve it. We show that it is instead a computational feature that is needed to encode some domains into default logic.

Abstract
Reiter's original definition of default logic allows for the application of a default that contradicts a previously applied one. We call this condition failure. The possibility of generating failures has been in the past considered as a semantical problem, and variants have been proposed to solve it. We show that it is instead a computational feature that is needed to encode some domains into default logic.File allegati a questo prodotto
