% 3.29/3.50 % SZS status Satisfiable
% 3.29/3.50 % SZS output start Proof
% 3.29/3.50 The input problem is satisfiable because
% 3.29/3.50
% 3.29/3.50 [1] the following set of Horn clauses is satisfiable:
% 3.29/3.50
% 3.29/3.50 ifeq(A, A, B, C) = B
% 3.29/3.50 n0 = s(X) ==> \bottom
% 3.29/3.50 ifeq(s(X), s(Y), X, Y) = Y
% 3.29/3.50 add(n0, Y) = Y
% 3.29/3.50 add(s(X), Y) = s(add(X, Y))
% 3.29/3.50 add(X, Y) = add(Y, X)
% 3.29/3.50
% 3.29/3.50 This holds because
% 3.29/3.50
% 3.29/3.50 [2] the following E does not entail the following G (Claessen-Smallbone's transformation (2018)):
% 3.29/3.50
% 3.29/3.50 E:
% 3.29/3.50 add(X, Y) = add(Y, X)
% 3.29/3.50 add(n0, Y) = Y
% 3.29/3.50 add(s(X), Y) = s(add(X, Y))
% 3.29/3.50 f1(n0) = false__
% 3.29/3.50 f1(s(X)) = true__
% 3.29/3.50 ifeq(A, A, B, C) = B
% 3.29/3.50 ifeq(s(X), s(Y), X, Y) = Y
% 3.29/3.50 G:
% 3.29/3.50 true__ = false__
% 3.29/3.50
% 3.29/3.50 This holds because
% 3.29/3.50
% 3.29/3.50 [3] the following ground-complete ordered TRS entails E but does not entail G:
% 3.29/3.50
% 3.29/3.50 add(X, Y) = add(Y, X)
% 3.29/3.50 s(add(Y1, Y0)) = s(add(Y0, Y1))
% 3.29/3.50 add(Y1, n0) -> Y1
% 3.29/3.50 add(Y1, s(Y0)) -> s(add(Y1, Y0))
% 3.29/3.50 add(n0, Y) -> Y
% 3.29/3.50 add(s(X), Y) -> s(add(X, Y))
% 3.29/3.50 f1(n0) -> false__
% 3.29/3.50 f1(s(X)) -> true__
% 3.29/3.50 ifeq(A, A, B, C) -> B
% 3.29/3.50 ifeq(s(X), s(Y), X, Y) -> Y
% 3.29/3.50 with the LPO induced by
% 3.29/3.50 ifeq > add > s > n0 > f1 > true__ > false__
