WebThen there exists a linear resolution proof of ?from the clauses P;G in which every clause is descended from the goal. Moreover, we can construct this proof so that, at each step, the last clause generated will have the form L 1 ^:::L n! ? and the next step is to resolve this with some rule of the form N !
