Dynamic belief revision operators

TLDR
The original Darwiche-Pearl approach is shown to be excessively strong and rather limited in scope, and a dynamic revision operator is provided via entrenchment kinematics as well as a simple form of lexicographic revision.

Iterated belief revision, revised

TL;DR: In this paper, the authors present a formal analysis of the deficiency of the standard postulates alone, and show how to solve the problem by an additional postulate of independence, which is compatible with AGM and DP.

AGM 25 Years : Twenty-Five Years of Research in Belief Change

TL;DR: The 1985 paper by Carlos Alchourrón, Peter Gärdenfors, and David Makinson, “On the Logic of Theory Change: Partial Meet Contraction and Revision Functions” was the starting-point of a large and rapidly growing literature that employs formal models in the investigation of changes in belief states and databases.

Shifting priorities: Simple representations for twenty-seven iterated theory change operators

TL;DR: It is shown how a shifting of priorities in prioritized bases can be used for a simple, constructive and intuitive way of representing a large variety of methods for the change of belief states—methods that have usually been characterized semantically by a system-of-spheres modeling.

Iterated revision as prioritized merging

TL;DR: This work argues that there is no reason, given a static world, for giving priority to more recent items, and suggests that a sequence of observations should be merged with the agent's beliefs.
Journal ArticleDOI

Admissible and restrained revision

TL;DR: It is demonstrated that restrained revision is the most conservative of admissible revision operators, effecting as few changes as possible, while lexicographic revision isThe least conservative, and the establishment of a principled approach for choosing an appropriate revision operator in different contexts is proposed.

On the logic of theory change: Partial meet contraction and revision functions

TL;DR: In this article, the authors extend earlier work by its authors on formal aspects of the processes of contracting a theory to eliminate a proposition and revising it to introduce a new proposition.

Nonmonotonic reasoning, preferential models and cumulative logics

TL;DR: In this paper, a number of families of nonmonotonic consequence relations, defined in the style of Gentzen [13], are studied from both proof-theoretic and semantic points of view.

Nonmonotonic Reasoning, Preferential Models and Cumulative Logics

TL;DR: The preferential models proposed here are a much stronger tool than Adams' probabilistic semantics, and are defined and characterized by representation theorems, relating the two points of view.

Knowledge in Flux: Modeling the Dynamics of Epistemic States

TL;DR: Knowledge in Flux presents a theory of rational changes of belief, focusing particularly on revisions that occur when the agent receives new information that is inconsistent with the present epistemic state.
