We define an abstract model of belief propagation on a graph based on the methodology of the revision theory of truth together with the Assertion Network Toolkit, a graphical inter...
This paper presents a logic-based bargaining solution based on Zhang and Zhang's framework. It is shown that if the demand sets of players are logically closed, the solution s...
Abstract. In this paper we investigate how to model legal abrogation and annulment in Defeasible Logic. We examine some options that embed in this setting, and similar rule-based s...
