% 15.52/2.38 Now clausify the problem and encode Horn clauses using encoding 3 of
% 15.52/2.38 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 15.52/2.38 We repeatedly replace C & s=t => u=v by the two clauses:
% 15.52/2.38 fresh(y, y, x1...xn) = u
% 15.52/2.38 C => fresh(s, t, x1...xn) = v
% 15.52/2.38 where fresh is a fresh function symbol and x1..xn are the free
% 15.52/2.38 variables of u and v.
% 15.52/2.38 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 15.52/2.38 input problem has no model of domain size 1).
% 15.52/2.38
% 15.52/2.38 The encoding turns the above axioms into the following unit equations and goals:
% 15.52/2.38
% 15.52/2.38 Axiom 1 (additive_identity2): sum(X, additive_identity, X) = true.
% 15.52/2.38 Axiom 2 (additive_identity1): sum(additive_identity, X, X) = true.

% 15.52/2.38 Axiom 20 (distributivity1): fresh24(X, X, Y, Z, W, V, U, T, S) = fresh25(sum(Z, V, T), true, W, U, S).
% 15.52/2.38 Axiom 21 (distributivity3): fresh16(X, X, Y, Z, W, V, U, T, S) = fresh17(sum(Y, V, T), true, W, U, S).
% 15.52/2.38 Axiom 22 (addition_is_well_defined): fresh4(sum(X, Y, Z), true, X, Y, W, Z) = fresh3(sum(X, Y, W), true, W, Z).

% 15.52/2.38 Axiom 25 (distributivity3): fresh14(X, X, Y, Z, W, V, U, T, S) = fresh15(product(Y, Z, W), true, Y, W, V, U, T, S).
% 15.52/2.38 Axiom 26 (distributivity1): fresh22(product(X, Y, Z), true, X, W, V, U, T, Y, Z) = fresh24(product(X, U, T), true, X, W, V, U, T, Y, Z).
% 15.52/2.38 Axiom 27 (distributivity3): fresh14(product(X, Y, Z), true, W, Y, V, U, T, X, Z) = fresh16(product(U, Y, T), true, W, Y, V, U, T, X, Z).
