% 0.17/0.39
% 0.17/0.39 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.17/0.39 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.17/0.39 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.17/0.39 fresh(y, y, x1...xn) = u
% 0.17/0.39 C => fresh(s, t, x1...xn) = v
% 0.17/0.39 where fresh is a fresh function symbol and x1..xn are the free
% 0.17/0.39 variables of u and v.
% 0.17/0.39 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.17/0.39 input problem has no model of domain size 1).
% 0.17/0.39
% 0.17/0.39 The encoding turns the above axioms into the following unit equations and goals:

% 0.17/0.39 Axiom 1 (tfree_tcs): class_Ring__and__Field_Oordered__idom(t_b) = true.

% 0.17/0.39 Axiom 16 (cls_Orderings_Oorder__class_Oorder__trans_0): fresh9(class_Orderings_Oorder(X), true, X, Y, Z, W) = fresh6(c_lessequals(W, Y, X), true, X, Y, Z, W).
