In Ref. [1], a conclusion was reached that input paramodulation refutation and unit paramodulation refutation are equivalent for a set of unit clauses, and a supposition was made that the converse of Theorem 8.4 is al...In Ref. [1], a conclusion was reached that input paramodulation refutation and unit paramodulation refutation are equivalent for a set of unit clauses, and a supposition was made that the converse of Theorem 8.4 is also true. In this note, we shall prove that both the conclusion and the supposition are wrong.展开更多
