% 0.13/0.39 % SZS output start Proof
% 0.13/0.39 The input problem is unsatisfiable because
% 0.13/0.39
% 0.13/0.39 [1] the following set of Horn clauses is unsatisfiable:
% 0.13/0.39
% 0.13/0.39 likes(A, bruce)
% 0.13/0.39 likes(A, B) ==> likes(lyle, A)
% 0.13/0.39 likes(A, sk1(A)) ==> \bottom
% 0.13/0.39
% 0.13/0.39 This holds because
% 0.13/0.39
% 0.13/0.39 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.13/0.39
% 0.13/0.39 E:
% 0.13/0.39 f1(likes(A, B), A) = true__
% 0.13/0.39 f1(true__, A) = likes(lyle, A)
% 0.13/0.39 f2(likes(A, sk1(A))) = true__
% 0.13/0.39 f2(true__) = false__
% 0.13/0.39 likes(A, bruce) = true__
% 0.13/0.39 G:
% 0.13/0.39 true__ = false__
% 0.13/0.39
% 0.13/0.39 This holds because
% 0.13/0.39
% 0.13/0.39 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.13/0.39
% 0.13/0.39
% 0.13/0.39 f1(f1(true__, Y1), lyle) -> true__
% 0.13/0.39 f1(likes(A, B), A) -> true__
% 0.13/0.39 f1(true__, Y0) -> true__
% 0.13/0.39 f1(true__, bruce) -> true__
% 0.13/0.39 f2(f1(true__, sk1(lyle))) -> true__
% 0.13/0.39 f2(likes(A, sk1(A))) -> true__
% 0.13/0.39 f2(true__) -> false__
% 0.13/0.39 false__ -> true__
% 0.13/0.39 likes(A, bruce) -> true__
% 0.13/0.39 likes(lyle, A) -> f1(true__, A)
% 0.13/0.39 with the LPO induced by
% 0.13/0.39 f2 > sk1 > lyle > bruce > likes > f1 > false__ > true__
