WebbKeep checking to see if we can use resolution to produce a new clause. If we ever produce the empty clause (equivalent to False), congratulations! We have arrived at a contradiction, thus proving that KB ⊨ α. However, if contradiction is not achieved and no more clauses can be inferred, there is no entailment.
