artificial intelligence, programming The kind of clause
used in logic programming which has no subgoals and so is
always true (always succeeds). E.g.
wet(water).
male(denis).
This is in contrast to a rule which only succeeds if all its
subgoals do. Rules usually contain logic variables, facts
rarely do, except for oddities like "equal(X,X).".
