Abstract

Accommodative revision is a novel method of non-prioritized belief revision. The epistemic state of an agent contains both knowledge that is immune to revision and beliefs that are allowed to change. Incoming information is first revised by the knowledge of the agent, and then the epistemic state of the agent is revised using this modified input. The properties of the method are studied and examples of its use are given.
