WebJul 25, 2024 · Here we can use the first definition, because David is a parent of John. In prolog, the definition looks like this: ancestor(A, B) :- parent(A, B). ancestor(A, B) :- parent(A, X), ancestor(X, B). The second rule is recursive; it uses ancestor to define ancestor. The first rule is called the stop predicate as it stops the predicate calling itself.
