ABDUCTIVE CHANGE OPERATORS
Jorge Lobo, Carlos Enrique Uzcategui · Fundamenta Informaticae · 1996
This paper describes a change theory based on abductive reasoning. We take the AGM postulates for revisions, expansions and contractions, and Katsuno and Mendelzon postulates for updates and incorporate abduction into them. A key feature of the theory is that presents a unified view of standard change operators and abductive change operators rather than a new and independent change theory for abductive changes. Abductive operators reduce to standard change operators in the limiting cases.
