fact
<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).".
