% 77.53/10.35 % SZS output start Proof
% 77.53/10.35 Take the following subset of the input axioms:
% 77.53/10.35 fof(axiom_1_2, axiom, ![A]: axiom(implies(or(A, A), A))).
% 77.53/10.35 fof(axiom_1_3, axiom, ![B, A2]: axiom(implies(A2, or(B, A2)))).
% 77.53/10.35 fof(axiom_1_4, axiom, ![A2, B2]: axiom(implies(or(A2, B2), or(B2, A2)))).
% 77.53/10.35 fof(axiom_1_5, axiom, ![C, A2, B2]: axiom(implies(or(A2, or(B2, C)), or(B2, or(A2, C))))).
% 77.53/10.35 fof(axiom_1_6, axiom, ![A2, B2, C2]: axiom(implies(implies(A2, B2), implies(or(C2, A2), or(C2, B2))))).
% 77.53/10.35 fof(implies_definition, axiom, ![X, Y]: implies(X, Y)=or(not(X), Y)).
% 77.53/10.35 fof(prove_this, negated_conjecture, ~theorem(implies(or(p, q), implies(or(not(p), q), q)))).
% 77.53/10.35 fof(rule_1, axiom, ![X2]: (theorem(X2) | ~axiom(X2))).
% 77.53/10.35 fof(rule_2, axiom, ![X2, Y2]: (theorem(X2) | (~theorem(implies(Y2, X2)) | ~theorem(Y2)))).
% 77.53/10.35
% 77.53/10.35 Now clausify the problem and encode Horn clauses using encoding 3 of
% 77.53/10.35 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 77.53/10.35 We repeatedly replace C & s=t => u=v by the two clauses:
% 77.53/10.35 fresh(y, y, x1...xn) = u
% 77.53/10.35 C => fresh(s, t, x1...xn) = v
% 77.53/10.35 where fresh is a fresh function symbol and x1..xn are the free
% 77.53/10.35 variables of u and v.
% 77.53/10.35 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 77.53/10.35 input problem has no model of domain size 1).
% 77.53/10.35
% 77.53/10.35 The encoding turns the above axioms into the following unit equations and goals:
% 77.53/10.35
% 77.53/10.35 Axiom 1 (implies_definition): implies(X, Y) = or(not(X), Y).
% 77.53/10.35 Axiom 2 (rule_2): fresh(X, X, Y) = true.
% 77.53/10.35 Axiom 3 (rule_1): fresh2(X, X, Y) = true.
% 77.53/10.35 Axiom 4 (rule_2): fresh3(X, X, Y, Z) = theorem(Y).
% 77.53/10.35 Axiom 5 (rule_1): fresh2(axiom(X), true, X) = theorem(X).
% 77.53/10.35 Axiom 6 (axiom_1_3): axiom(implies(X, or(Y, X))) = true.
% 77.53/10.35 Axiom 7 (axiom_1_2): axiom(implies(or(X, X), X)) = true.
% 77.53/10.35 Axiom 8 (axiom_1_4): axiom(implies(or(X, Y), or(Y, X))) = true.
% 77.53/10.35 Axiom 9 (rule_2): fresh3(theorem(implies(X, Y)), true, Y, X) = fresh(theorem(X), true, Y).
% 77.53/10.35 Axiom 10 (axiom_1_6): axiom(implies(implies(X, Y), implies(or(Z, X), or(Z, Y)))) = true.
