Abstract
In this paper, we present a general schema for de ning new update semantics. This schema takes as input any basic logic programming semantics, such as the stable semantics, the p-stable semantics or the MMr semantics, and gives as output a new update semantics. The schema proposed is based on a concept called minimal generalized S models, where S is any of the logic programming semantics. Each update semantics is associated to an update operator. We also present some properties of these update operators.
Highlights
Updating, by definition means that there is new information that must be added to the older, and some information could be changed
Each update semantics is associated to an update operator
In terms of logic programming semantics, we present the definition of the stable model semantics, the p-stable model semantics, and the M M r semantics
