Answer Sets in a Fuzzy Equilibrium Logic [chapter]

Steven Schockaert, Jeroen Janssen, Dirk Vermeir, Martine De Cock
2009 Lecture Notes in Computer Science  
In this paper, we combine the expressiveness of both approaches, and define answer sets of arbitrary fuzzy propositional theories as models in a fuzzification of equilibrium logic.  ...  As one of the most general "classical" approaches, answer sets of arbitrary propositional theories can be defined as models in the equilibrium logic of Pearce.  ...  Acknowledgments Steven Schockaert was funded as a postdoctoral fellow of the Research Foundation -Flanders. Jeroen Janssen was funded by a joint Research Foundation -Flanders project.  ...

Stable Models of Fuzzy Propositional Formulas [chapter]

Joohyung Lee, Yi Wang
2014 Lecture Notes in Computer Science  
We introduce the stable model semantics for fuzzy propositional formulas, which generalizes both fuzzy propositional logic and the stable model semantics of Boolean propositional formulas.  ...  We show that several properties of Boolean stable models are naturally extended to this formalism, and discuss how it is related to other approaches to combining fuzzy logic and the stable model semantics  ...  However, the semantics of fuzzy logic is monotonic and is not flexible enough to handle default reasoning as allowed in answer set programming.  ...

Fuzzy autoepistemic logic and its relation to fuzzy answer set programming

Marjon Blondeel, Steven Schockaert, Martine De Cock, Dirk Vermeir
2014 Fuzzy sets and systems (Print)  
In this paper, we consider a version of fuzzy answer set programming and show that its answer sets can be equivalently described as models in fuzzy autoepistemic logic.  ...  We also define a fuzzy logic of minimal belief and negation-as-failure and use this as a tool to show that fuzzy autoepistemic logic generalizes fuzzy answer set programming.  ...  In [34] a correspondence between fuzzy equilibrium logic models and answer sets of FASP programs was shown.  ...
