A New Approach for Revising Logic Programs
Zhiqiang Zhuang, James Delgrande, Abhaya Nayak +1
Belief revision has been studied mainly with respect to background logics that are monotonic in character. In this paper we study belief revision when the underlying logic is non-m…
An Approach to Forgetting in Disjunctive Logic Programs that Preserves Strong Equivalence
James P. Delgrande, Kewen Wang
In this paper we investigate forgetting in disjunctive logic programs, where forgetting an atom from a program amounts to a reduction in the signature of that program. The goal is…
Iterated Belief Change Due to Actions and Observations
Aaron Hunter, James P. Delgrande
In action domains where agents may have erroneous beliefs, reasoning about the effects of actions involves reasoning about belief change. In this paper, we use a transition system…
Compositional Belief Update
James Delgrande, Yi Jin, Francis Jeffry Pelletier
In this paper we explore a class of belief update operators, in which the definition of the operator is compositional with respect to the sentence to be added. The goal is to provi…
A Program-Level Approach to Revising Logic Programs under the Answer Set Semantics
James P. Delgrande
An approach to the revision of logic programs under the answer set semantics is presented. For programs P and Q, the goal is to determine the answer sets that correspond to the rev…
A general approach to belief change in answer set programming
James Delgrande, Torsten Schaub, Hans Tompits +1
We address the problem of belief change in (nonmonotonic) logic programming under answer set semantics. Unlike previous approaches to belief change in logic programming, our formal…
