% 204.23/26.54
% 204.23/26.54 Now clausify the problem and encode Horn clauses using encoding 3 of
% 204.23/26.54 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 204.23/26.54 We repeatedly replace C & s=t => u=v by the two clauses:
% 204.23/26.54 fresh(y, y, x1...xn) = u
% 204.23/26.54 C => fresh(s, t, x1...xn) = v
% 204.23/26.54 where fresh is a fresh function symbol and x1..xn are the free
% 204.23/26.54 variables of u and v.
% 204.23/26.54 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 204.23/26.54 input problem has no model of domain size 1).
% 204.23/26.54
% 204.23/26.54 The encoding turns the above axioms into the following unit equations and goals:
% 204.23/26.54
% 204.23/26.54 Axiom 1 (cls_nat__mult__1_0): hAPP(hAPP(c_HOL_Otimes__class_Otimes(tc_nat), c_HOL_Oone__class_Oone(tc_nat)), X) = X.
% 204.23/26.54 Axiom 2 (cls_plus__nat_Oadd__0_0): hAPP(hAPP(c_HOL_Oplus__class_Oplus(tc_nat), c_HOL_Ozero__class_Ozero(tc_nat)), X) = X.
% 204.23/26.54 Axiom 3 (cls_COMBB__def_0): hAPP(c_COMBB(X, Y, Z, W, V), U) = hAPP(X, hAPP(Y, U)).
% 204.23/26.54 Axiom 4 (cls_COMBS__def_0): hAPP(c_COMBS(X, Y, Z, W, V), U) = hAPP(hAPP(X, U), hAPP(Y, U)).
% 204.23/26.54
% 204.23/26.54 Goal 1 (cls_n__not__Suc__n_0): X = hAPP(c_Suc, X).
% 204.23/26.54 The goal is true when:
% 204.23/26.54 X = hAPP(c_COMBS(hAPP(c_HOL_Oplus__class_Oplus(tc_nat), c_HOL_Ozero__class_Ozero(tc_nat)), hAPP(c_HOL_Oplus__class_Oplus(tc_nat), c_HOL_Ozero__class_Ozero(tc_nat)), X, Y, Z), c_COMBB(c_Suc, c_COMBS(hAPP(c_HOL_Oplus__class_Oplus(tc_nat), c_HOL_Ozero__class_Ozero(tc_nat)), hAPP(c_HOL_Oplus__class_Oplus(tc_nat), c_HOL_Ozero__class_Ozero(tc_nat)), X, Y, Z), W, V, U))
