Understanding Resolution Theorem Proving in Predicate Logic
Resolution theorem proving is a method used in predicate logic to find contradictions within a database of clauses. By negating statements and applying resolution rule of inference, it aims to show inconsistency to prove the original theorem. The process involves putting premises into clause form, a
