% 0.21/0.45    fof(cls_Ring__and__Field_Opordered__semiring__class_Omult__right__mono_0, axiom, ![V_b, V_c, T_a2, V_a2]: (~class_Ring__and__Field_Opordered__semiring(T_a2) | (~c_lessequals(V_a2, V_b, T_a2) | (~c_lessequals(c_0, V_c, T_a2) | c_lessequals(c_times(V_a2, V_c, T_a2), c_times(V_b, V_c, T_a2), T_a2))))).

% 0.21/0.45  
% 0.21/0.45  Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.21/0.45  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.21/0.45  We repeatedly replace C & s=t => u=v by the two clauses:
% 0.21/0.45    fresh(y, y, x1...xn) = u
% 0.21/0.45    C => fresh(s, t, x1...xn) = v
% 0.21/0.45  where fresh is a fresh function symbol and x1..xn are the free
% 0.21/0.45  variables of u and v.
% 0.21/0.45  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.21/0.45  input problem has no model of domain size 1).
% 0.21/0.45  
% 0.21/0.45  The encoding turns the above axioms into the following unit equations and goals:
% 0.21/0.45  
% 0.21/0.45  Axiom 1 (tfree_tcs): class_Ring__and__Field_Oordered__idom(t_a) = true.

% 0.21/0.45  Axiom 16 (cls_Ring__and__Field_Opordered__semiring__class_Omult__right__mono_0): fresh4(X, X, Y, Z, W, V) = c_lessequals(c_times(Z, W, Y), c_times(V, W, Y), Y).
% 0.21/0.45  Axiom 17 (cls_Ring__and__Field_Opordered__semiring__class_Omult__right__mono_0): fresh8(X, X, Y, Z, W, V) = fresh9(c_lessequals(Z, V, Y), true, Y, Z, W, V).
