In this article we consider the use of hints to help guide the search for a proof. Under the hints strategy, the value of a generated clause is determined, in part, by whether or not the clause subsumes or is subsumed by a user-supplied hint clause. We have implemented the hints strategy and have experimented with it extensively. We summarize our experiences for a variety of reasoning tasks, including proof checking, proof completion, and proof finding. We conclude that the hints strategy has value beyond simply “giving the proof to find the proof.”
