% 0.79/1.00  % SZS status Unsatisfiable
% 0.79/1.00  % SZS output start Proof
% 0.79/1.00  The input problem is unsatisfiable because
% 0.79/1.00  
% 0.79/1.00  [1] the following set of Horn clauses is unsatisfiable:
% 0.79/1.00  
% 0.79/1.00  	implies(truth, X) = X
% 0.79/1.00  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 0.79/1.00  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 0.79/1.00  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 0.79/1.00  	implies(X, Y) = implies(Y, X)
% 0.79/1.00  	x = y ==> \bottom
% 0.79/1.00  
% 0.79/1.00  This holds because
% 0.79/1.00  
% 0.79/1.00  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.79/1.00  
% 0.79/1.00  E:
% 0.79/1.00  	f1(x) = true__
% 0.79/1.00  	f1(y) = false__
% 0.79/1.00  	implies(X, Y) = implies(Y, X)
% 0.79/1.00  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 0.79/1.00  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 0.79/1.00  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 0.79/1.00  	implies(truth, X) = X
% 0.79/1.00  G:
% 0.79/1.00  	true__ = false__
% 0.79/1.00  
% 0.79/1.00  This holds because
% 0.79/1.00  
% 0.79/1.00  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.79/1.00  
% 0.79/1.00  	X0 = Y0
% 0.79/1.00  	Y0 = truth
% 0.79/1.00  	false__ = Y0
% 0.79/1.00  	implies(X, Y) = implies(Y, X)
% 0.79/1.00  	implies(Y1, Y1) = implies(Y1, truth)
% 0.79/1.00  	implies(Y1, implies(Y0, Y1)) = implies(Y0, implies(Y1, Y0))
% 0.79/1.00  	implies(Y1, implies(Y1, Y0)) = implies(Y0, implies(Y1, Y0))
% 0.79/1.00  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 0.79/1.00  	f1(x) -> true__
% 0.79/1.00  	f1(y) -> false__
% 0.79/1.00  	implies(Y0, Y0) -> Y0
% 0.79/1.00  	implies(Y0, Y2) -> truth
% 0.79/1.00  	implies(Y0, implies(Y1, implies(Y1, Y0))) -> truth
% 0.79/1.00  	implies(Y0, implies(not(Y0), not(truth))) -> truth
% 0.79/1.00  	implies(Y0, implies(not(truth), not(Y0))) -> truth
% 0.79/1.00  	implies(Y0, not(Y0)) -> truth
% 0.79/1.00  	implies(Y1, Y1) -> truth
% 0.79/1.00  	implies(Y1, implies(Y1, Y1)) -> implies(Y1, Y1)
% 0.79/1.00  	implies(Y1, implies(Y1, Y1)) -> truth
% 0.79/1.00  	implies(Y1, implies(Y2, implies(Y1, Y2))) -> truth
% 0.79/1.00  	implies(Y1, truth) -> Y1
% 0.79/1.00  	implies(Y2, implies(Y2, implies(Y0, Y2))) -> truth
% 0.79/1.00  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) -> truth
% 0.79/1.00  	implies(implies(Y0, truth), implies(Y2, implies(Y0, Y2))) -> truth
% 0.79/1.00  	implies(implies(Y1, Y0), implies(not(Y0), not(Y1))) -> truth
% 0.79/1.00  	implies(implies(Y2, Y1), implies(Y2, implies(Y1, Y2))) -> truth
% 0.79/1.00  	implies(implies(not(X), not(Y)), implies(Y, X)) -> truth
% 0.79/1.00  	implies(truth, X) -> X
% 0.79/1.00  	not(Y1) -> truth
% 0.79/1.00  	not(truth) -> truth
% 0.79/1.00  	true__ -> false__
% 0.79/1.00  with the LPO induced by
% 0.79/1.00  	x > y > f1 > not > implies > truth > true__ > false__
