In the refinement calculus, monotonic predicate transformers are used to model specifications for (imperative) programs. Together with a natural notion of simulation, they form a...
Abstract. The ability to view extended logic programs as argumentation systems opens the way for the use of this language in formalizing communication among reasoning computing age...
In recent years, fuzzy logic has been applied successfully to a wide range of problems. This paper shows how it can be utilized in the area of spatial reasoning, in particular geo...
