% 0.18/0.37  The input problem is unsatisfiable because
% 0.18/0.37  
% 0.18/0.37  [1] the following set of Horn clauses is unsatisfiable:
% 0.18/0.37  
% 0.18/0.37  	c_in(v_u, c_Mutil_Otiling(v_A, t_a), tc_set(t_a))
% 0.18/0.37  	c_in(c_union(c_emptyset, v_u, t_a), c_Mutil_Otiling(v_A, t_a), tc_set(t_a)) ==> \bottom
% 0.18/0.37  	c_union(c_emptyset, V_y, T_a) = V_y
% 0.18/0.37  
% 0.18/0.37  This holds because
% 0.18/0.37  
% 0.18/0.37  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.18/0.37  
% 0.18/0.37  E:
% 0.18/0.37  	c_in(v_u, c_Mutil_Otiling(v_A, t_a), tc_set(t_a)) = true__
% 0.18/0.37  	c_union(c_emptyset, V_y, T_a) = V_y
% 0.18/0.37  	f1(c_in(c_union(c_emptyset, v_u, t_a), c_Mutil_Otiling(v_A, t_a), tc_set(t_a))) = true__
% 0.18/0.37  	f1(true__) = false__
% 0.18/0.37  G:
% 0.18/0.37  	true__ = false__
% 0.18/0.37  
% 0.18/0.37  This holds because
% 0.18/0.37  
% 0.18/0.37  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.18/0.37  
% 0.18/0.37  
% 0.18/0.37  	c_in(v_u, c_Mutil_Otiling(v_A, t_a), tc_set(t_a)) -> true__

% 0.18/0.37  	f1(true__) -> false__
% 0.18/0.37  	false__ -> true__
% 0.18/0.37  with the LPO induced by
% 0.18/0.37  	c_emptyset > c_union > f1 > tc_set > t_a > v_A > c_Mutil_Otiling > v_u > c_in > false__ > true__
