Abstract. Considering different implication operators, such as Lukasiewicz, G¨odel or product implication in the same logic program, naturally leads to the allowance of several a...
Gelfond and Lifschitz introduce a declarative language A for describing effects of actions and define a translation of theories in this language into extended logic programs(ELP, ...
In this paper we give a summary of our recent survey of practical applications of Logic Programming in Italy. The survey covers a 25 year time-span. Information was mainly gathere...
In this tutorial the specialisation of declarative logic programs is presented. The main correctness results are given, and the outline of a basic algorithm for partial evaluation...
We study properties of programs with monotone and convex constraints. We extend to these formalisms concepts and results from normal logic programming. They include the notions of...
