% 0.12/0.38  % SZS output start Proof
% 0.12/0.38  The input problem is unsatisfiable because
% 0.12/0.38  
% 0.12/0.38  [1] the following set of Horn clauses is unsatisfiable:
% 0.12/0.38  
% 0.12/0.38  	f(b, z1(Y1, Y2))
% 0.12/0.38  	f(Y1, z2(Y1, Y2))
% 0.12/0.38  	f(Y1, z1(Y1, Y2)) & f(Y2, z1(Y1, Y2)) ==> \bottom
% 0.12/0.38  	f(b, z2(Y1, Y2)) & f(Y2, z2(Y1, Y2)) ==> \bottom
% 0.12/0.38  
% 0.12/0.38  This holds because
% 0.12/0.38  
% 0.12/0.38  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.12/0.38  
% 0.12/0.38  E:
% 0.12/0.38  	f(Y1, z2(Y1, Y2)) = true__
% 0.12/0.38  	f(b, z1(Y1, Y2)) = true__
% 0.12/0.38  	f1(true__) = false__
% 0.12/0.38  	f2(f(Y2, z1(Y1, Y2)), Y1, Y2) = true__
% 0.12/0.38  	f2(true__, Y1, Y2) = f1(f(Y1, z1(Y1, Y2)))
% 0.12/0.38  	f3(true__) = false__
% 0.12/0.38  	f4(f(Y2, z2(Y1, Y2)), Y1, Y2) = true__
% 0.12/0.38  	f4(true__, Y1, Y2) = f3(f(b, z2(Y1, Y2)))
% 0.12/0.38  G:
% 0.12/0.38  	true__ = false__
% 0.12/0.38  
% 0.12/0.38  This holds because
% 0.12/0.38  
% 0.12/0.38  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.12/0.38  
% 0.12/0.38  
% 0.12/0.38  	f(Y1, z2(Y1, Y2)) -> true__
% 0.12/0.38  	f(b, z1(Y1, Y2)) -> true__
% 0.12/0.38  	f1(f(Y1, z1(Y1, Y2))) -> f2(true__, Y1, Y2)
% 0.12/0.38  	f1(true__) -> false__
% 0.12/0.38  	f2(f(Y2, z1(Y1, Y2)), Y1, Y2) -> true__
% 0.12/0.38  	f2(true__, Y1, b) -> true__
% 0.12/0.38  	f2(true__, b, Y1) -> false__
% 0.12/0.38  	f3(f(b, z2(Y1, Y2))) -> f4(true__, Y1, Y2)
% 0.12/0.38  	f3(true__) -> false__
% 0.12/0.38  	f4(f(Y2, z2(Y1, Y2)), Y1, Y2) -> true__
% 0.12/0.38  	f4(true__, Y1, Y1) -> true__
% 0.12/0.38  	f4(true__, b, Y1) -> false__
% 0.12/0.38  	false__ -> true__
% 0.12/0.38  with the LPO induced by
% 0.12/0.38  	f1 > f > f4 > z2 > f2 > b > f3 > z1 > false__ > true__
