% 238.46/30.49
% 238.46/30.49 Now clausify the problem and encode Horn clauses using encoding 3 of
% 238.46/30.49 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 238.46/30.49 We repeatedly replace C & s=t => u=v by the two clauses:
% 238.46/30.49 fresh(y, y, x1...xn) = u
% 238.46/30.49 C => fresh(s, t, x1...xn) = v
% 238.46/30.49 where fresh is a fresh function symbol and x1..xn are the free
% 238.46/30.49 variables of u and v.
% 238.46/30.49 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 238.46/30.49 input problem has no model of domain size 1).
% 238.46/30.49
% 238.46/30.49 The encoding turns the above axioms into the following unit equations and goals:
% 238.46/30.49
% 238.46/30.49 Axiom 1 (clsarity_nat_3): class_Orderings_Oorder(tc_nat) = true2.
% 238.46/30.49 Axiom 2 (cls_conjecture_1): v_x(X) = v_nat.
% 238.46/30.49 Axiom 3 (cls_conjecture_0): c_lessequals(X, v_x(X), tc_nat) = true2.
% 238.46/30.49 Axiom 4 (cls_SetInterval_OatLeastLessThan__singleton_0): c_SetInterval_OatLeastLessThan(X, c_Suc(X), tc_nat) = c_insert(X, c_emptyset, tc_nat).
% 238.46/30.49 Axiom 5 (cls_SetInterval_OatLeastLessThan__empty_0): fresh1209(X, X, Y, Z, W) = c_emptyset.
% 238.46/30.49 Axiom 6 (cls_SetInterval_OatLeastLessThan__empty_0): fresh1208(X, X, Y, Z, W) = c_SetInterval_OatLeastLessThan(W, Z, Y).
% 238.46/30.49 Axiom 7 (cls_SetInterval_OatLeastLessThan__empty_0): fresh1208(class_Orderings_Oorder(X), true2, X, Y, Z) = fresh1209(c_lessequals(Y, Z, X), true2, X, Y, Z).
% 238.46/30.49
% 238.46/30.49 Goal 1 (cls_Set_Oempty__not__insert_0): c_emptyset = c_insert(X, Y, Z).
% 238.46/30.49 The goal is true when:
% 238.46/30.49 X = v_nat
% 238.46/30.49 Y = c_emptyset
% 238.46/30.49 Z = tc_nat
% 238.46/30.49
% 238.46/30.49 Proof:
% 238.46/30.49 c_emptyset
% 238.46/30.49 = { by axiom 5 (cls_SetInterval_OatLeastLessThan__empty_0) R->L }
% 238.46/30.49 fresh1209(true2, true2, tc_nat, c_Suc(v_nat), v_nat)
% 238.46/30.49 = { by axiom 3 (cls_conjecture_0) R->L }
% 238.46/30.49 fresh1209(c_lessequals(c_Suc(v_nat), v_x(c_Suc(v_nat)), tc_nat), true2, tc_nat, c_Suc(v_nat), v_nat)
% 238.46/30.49 = { by axiom 2 (cls_conjecture_1) }
% 238.46/30.49 fresh1209(c_lessequals(c_Suc(v_nat), v_nat, tc_nat), true2, tc_nat, c_Suc(v_nat), v_nat)
% 238.46/30.49 = { by axiom 7 (cls_SetInterval_OatLeastLessThan__empty_0) R->L }
% 238.46/30.49 fresh1208(class_Orderings_Oorder(tc_nat), true2, tc_nat, c_Suc(v_nat), v_nat)
% 238.46/30.49 = { by axiom 1 (clsarity_nat_3) }
% 238.46/30.49 fresh1208(true2, true2, tc_nat, c_Suc(v_nat), v_nat)
% 238.46/30.49 = { by axiom 6 (cls_SetInterval_OatLeastLessThan__empty_0) }
% 238.46/30.49 c_SetInterval_OatLeastLessThan(v_nat, c_Suc(v_nat), tc_nat)
% 238.46/30.49 = { by axiom 4 (cls_SetInterval_OatLeastLessThan__singleton_0) }
% 238.46/30.49 c_insert(v_nat, c_emptyset, tc_nat)
% 238.46/30.49 % SZS output end Proof
% 238.46/30.49
% 238.46/30.49 RESULT: Unsatisfiable (the axioms are contradictory).
