15. Unifiers and unification Write the most general unifier (MGU) of the two terms given, or "None" if no unification is possible. Write your answer in the form of a substitution as discussed in the class. Universally quantified variables are indicated by?'s. The first one is done for you as an example a. UNIFY( P(John, ?x), P(John, Jane)) x/Jane b. UNIFY( P(?x, 2), P(1, 2, 3)) c. UNIFY( P(?y, ?x), P(John, Jane)) d. UNIFY(P(2x), Q(I)) e. UNIFY(P(?x, 2y, ?z), P, 2), f(g(a,b))) f. UNIFY( P(John, f?x) ), P(?y, f?y))) 15. Unifiers and unification Write the most general unifier (MGU) of the two terms given, or "None" if no unification is possible.
