Sep 4, 2021 · Hi Jan, Hi all, I come back with something else I do not understand related to the well founded semantics (WFS).
We introduce global SLS-resolution, a procedural semantics for well-founded negation as defined by Van Gelder, Ross, and Schlipf.
Sep 3, 2021 · I meant including constructive negation only into WFS. But maybe this is inherently associated to stable models. I'm not a logician either. jan:.
Abstract. A general logic program (abbreviated to \program" hereafter) is a set of rules that have both positive and negative subgoals.
A standard approach to negation in logic programming is negation as failure. Its major drawback is that it cannot produce answer substitutions to negated q.
The basic idea of our method is that in order to. ¬A with respect to a program P a answer a query ← fail answer for PU{A} is found. A fail answer is.
