% 32.79/32.84 % SZS status Unsatisfiable
% 32.79/32.84 % SZS output start Proof
% 32.79/32.84 The input problem is unsatisfiable because
% 32.79/32.84
% 32.79/32.84 [1] the following set of Horn clauses is unsatisfiable:
% 32.79/32.84
% 32.79/32.84 implies(truth, X) = X
% 32.79/32.84 implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 32.79/32.84 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 32.79/32.84 implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 32.79/32.84 implies(not(a), implies(b, not(implies(b, a)))) = truth ==> \bottom
% 32.79/32.84
% 32.79/32.84 This holds because
% 32.79/32.84
% 32.79/32.84 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 32.79/32.84
% 32.79/32.84 E:
% 32.79/32.84 f1(implies(not(a), implies(b, not(implies(b, a))))) = true__
% 32.79/32.84 f1(truth) = false__
% 32.79/32.84 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 32.79/32.84 implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 32.79/32.84 implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 32.79/32.84 implies(truth, X) = X
% 32.79/32.84 G:
% 32.79/32.84 true__ = false__
% 32.79/32.84
% 32.79/32.84 This holds because
% 32.79/32.84
% 32.79/32.84 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
