% 6.61/6.65 % SZS status Unsatisfiable
% 6.61/6.65 % SZS output start Proof
% 6.61/6.65 The input problem is unsatisfiable because
% 6.61/6.65
% 6.61/6.65 [1] the following set of Horn clauses is unsatisfiable:
% 6.61/6.65
% 6.61/6.65 axiom(or(not(or(A, A)), A))
% 6.61/6.65 axiom(or(not(A), or(B, A)))
% 6.61/6.65 axiom(or(not(or(A, B)), or(B, A)))
% 6.61/6.65 axiom(or(not(or(A, or(B, C))), or(B, or(A, C))))
% 6.61/6.65 axiom(or(not(or(not(A), B)), or(not(or(C, A)), or(C, B))))
% 6.61/6.65 axiom(X) ==> theorem(X)
% 6.61/6.65 axiom(or(not(Y), X)) & theorem(Y) ==> theorem(X)
% 6.61/6.65 axiom(or(not(X), Y)) & theorem(or(not(Y), Z)) ==> theorem(or(not(X), Z))
% 6.61/6.65 theorem(or(not(p), p)) ==> \bottom
% 6.61/6.65
% 6.61/6.65 This holds because
% 6.61/6.65
% 6.61/6.65 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 6.61/6.65
% 6.61/6.65 E:
% 6.61/6.65 axiom(or(not(A), or(B, A))) = true__
% 6.61/6.65 axiom(or(not(or(A, A)), A)) = true__
% 6.61/6.65 axiom(or(not(or(A, B)), or(B, A))) = true__
% 6.61/6.65 axiom(or(not(or(A, or(B, C))), or(B, or(A, C)))) = true__
% 6.61/6.65 axiom(or(not(or(not(A), B)), or(not(or(C, A)), or(C, B)))) = true__
% 6.61/6.65 f1(axiom(X), X) = true__
% 6.61/6.65 f1(true__, X) = theorem(X)
% 6.61/6.65 f2(true__, X) = theorem(X)
% 6.61/6.65 f3(theorem(Y), Y, X) = true__
% 6.61/6.65 f3(true__, Y, X) = f2(axiom(or(not(Y), X)), X)
% 6.61/6.65 f4(true__, X, Z) = theorem(or(not(X), Z))
% 6.61/6.65 f5(theorem(or(not(Y), Z)), X, Y, Z) = true__
% 6.61/6.65 f5(true__, X, Y, Z) = f4(axiom(or(not(X), Y)), X, Z)
% 6.61/6.65 f6(theorem(or(not(p), p))) = true__
% 6.61/6.65 f6(true__) = false__
% 6.61/6.65 G:
% 6.61/6.65 true__ = false__
% 6.61/6.65
% 6.61/6.65 This holds because
% 6.61/6.65
% 6.61/6.65 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
