Learn how to use SWI‑Prolog’s tabling (SLG resolution) to memoize recursive predicates, illustrated with a Fibonacci example, including benefits, trade‑offs, and verification steps.
Left-recursive reachability loops under plain Prolog. Tabling (SLG resolution) fixes that with one directive — here's when it's the right call, and what it costs.
Prolog tabling transforms SLD resolution into SLG resolution, caching subgoal answers to avoid redundant computation. This article covers when to enable it, trust boundaries, operational checks, and failure modes to help you decide if memoization fits your project.
