% 0.18/0.38 % SZS output start Proof
% 0.18/0.38 The input problem is unsatisfiable because
% 0.18/0.38
% 0.18/0.38 [1] the following set of Horn clauses is unsatisfiable:
% 0.18/0.38
% 0.18/0.38 p(A, B)
% 0.18/0.38 p(f(A, B), f(A, B)) & p(B, f(A, B)) ==> q(A, B)
% 0.18/0.38 q(f(A, B), f(A, B)) & q(A, f(A, B)) & p(f(A, B), f(A, B)) & p(B, f(A, B)) ==> \bottom
% 0.18/0.38
% 0.18/0.38 This holds because
% 0.18/0.38
% 0.18/0.38 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.18/0.38
% 0.18/0.38 E:
% 0.18/0.38 f1(true__, A, B) = q(A, B)
% 0.18/0.38 f2(p(B, f(A, B)), A, B) = true__

% 0.18/0.38 G:
% 0.18/0.38 true__ = false__
% 0.18/0.38
% 0.18/0.38 This holds because
