We establish the complexity of decision problems associated with the nonmonotonic modal logic S4. We prove that the problem of existence of an S4-expansion for a given set A of pr...
This paper considers the problem of adding list as a type constructor to an object-oriented data model. In particular, we are concerned with how lists in a database can be constru...
We re-examine vacuity in temporal logic model checking. We note two disturbing phenomena in recent results in this area. The first indicates that not all vacuities detected in prac...
Qualitative Coalitional Games (QCGs) are a version of coalitional games in which an agent's desires are represented as goals which are either satisfied or unsatisfied, and ea...
Structure identification is one of the most significant steps in Fuzzy modeling of a complex system. Efficient structure identification requires good approximation of the effectiv...
