Hand-Writing Program Generator Generators
In this paper we argue that hand-writing a program generator generator has a number of advantages compared to generating a program generator generator by self-application of a part...

Combining Lazy Narrowing with Disequality Constraints
Abstract. We investigate an extension of a lazy functional logic language, which uses term disequations both in programs and in computed answers. The semantic properties of the lan...

Computing Stable and Partial Stable Models of Extended Disjunctive Logic Programs
In Prz91], Przymusinski introduced the partial (or 3-valued) stable model semantics which extends the (2-valued) stable model semantics dened originally by Gelfond and Lifschitz G...

Static Semantics as Program Transformation and Well-founded Computation
In this paper, we propose a new constructive characterization of those semantics for disjunctive logic programs which are extensions of the well-founded semantics for normal progra...
