On Generalizing the AGM Postulates
The AGM theory is the dominating paradigm in the field of belief change but makes some non-elementary assumptions which disallow its application to certain logics. In this paper, we recast the theory by dropping most such assumptions; we determine necessary and sufficient conditions for a logic to support operators which are compatible with our generalized version of the theory and show that ou...
متن کاملRanking Functions, AGM Style
Ranking functions, having their first appearance under the name „ordinale Konditionalfunktionen“ in my Habilitationsschrift submitted in 1983, had several precursors of which I was only incompletely aware, among them Shackle’s functions of potential surprise (see Shackle 1969), Rescher’s plausibility indexing (see Rescher 1976), Adams’ ε-semantics (see Adams 1975), Cohen’s inductive probabiliti...
متن کاملIterable AGM functions
Appeared in Proceedings of BR'98. Trento. Italy. The AGM model has been criticized for not addressing the problem of iterated change. This is true, but in some cases the invalid claim that \AGM does not allow iteration" has been made. In this paper we examine the most elementary scheme of iteration: an iterable function. We formulate an iterable version of the AGM model, showing that the AGM fo...
متن کاملAGM postulates in Answer Sets
Revising and updating beliefs and knowledge bases is an important topic in knowledge representation and reasoning that requires a solid theoretical basis. As a result, various researchers have proposed Answer Set Programming as one of their key components to set up their approaches. In the need to satisfy more general principles, this paper presents a new characterisation of a semantics. It con...
متن کاملAGM Theory and Artificial Intelligence
A very influential work on belief change is based on the seminal paper ‘On the Logic of Theory Change: Partial Meet Contractions and Revision Functions’. In this paper Alchourron, Gärdenfors, and Makinson investigate the properties that such a method should have in order to be intuitively appealing. The result was a set of postulates (named AGM postulates after the initials of the authors) that...
