Knowledge updates: Semantics and complexity issues
We consider the problem of how an agent's knowledge can be updated. We propose a formal method of knowledge update on the basis of the semantics of modal logic S5. In our met...

Taxonomy of Improvement Operators and the Problem of Minimal Change
Improvement operators is a family of belief change operators that is a generalization of usual iterated belief revision operators. The idea is to relax the success property, so th...
