% 0.20/0.50
% 0.20/0.50 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.20/0.50 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.20/0.50 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.20/0.50 fresh(y, y, x1...xn) = u
% 0.20/0.50 C => fresh(s, t, x1...xn) = v
% 0.20/0.50 where fresh is a fresh function symbol and x1..xn are the free
% 0.20/0.50 variables of u and v.
% 0.20/0.50 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.20/0.50 input problem has no model of domain size 1).
% 0.20/0.50
% 0.20/0.50 The encoding turns the above axioms into the following unit equations and goals:
% 0.20/0.50
% 0.20/0.50 Axiom 1 (tfree_tcs): class_Ring__and__Field_Oordered__idom(t_b) = true2.

% 0.20/0.50
% 0.20/0.50 Goal 1 (cls_conjecture_1): c_lessequals(c_HOL_Oabs(c_times(v_c, v_b(v_x(X)), t_b), t_b), c_times(X, c_HOL_Oabs(v_f(v_x(X)), t_b), t_b), t_b) = true2.
