Query Evaluation under the Well Founded Semantics (Extended Abstract)
Summary: SLG: a goal-directed extension of SLDNF that tables transformations to avoid positive/negative loops and repeated evaluation, ensuring termination for bounded-term-size programs. Sound and ideally complete for non‑floundering queries under three‑valued (incl. well‑founded) semantics, polytime data complexity for well‑founded negation, and Prolog-compatible.
