% 68.73/9.08 % SZS output start Proof
% 68.73/9.08 Take the following subset of the input axioms:
% 68.73/9.08 fof(cls_Message_Oanalz__mono_0, axiom, ![V_G, V_H]: (~c_lessequals(V_G, V_H, tc_set(tc_Message_Omsg)) | c_lessequals(c_Message_Oanalz(V_G), c_Message_Oanalz(V_H), tc_set(tc_Message_Omsg)))).
% 68.73/9.08 fof(cls_Set_OUn__upper1_0, axiom, ![T_a, V_A, V_B]: c_lessequals(V_A, c_union(V_A, V_B, T_a), tc_set(T_a))).
% 68.73/9.08 fof(cls_Set_OUn__upper2_0, axiom, ![T_a2, V_A2, V_B2]: c_lessequals(V_B2, c_union(V_A2, V_B2, T_a2), tc_set(T_a2))).
% 68.73/9.08 fof(cls_Set_Osubset__trans_0, axiom, ![V_C, T_a2, V_A2, V_B2]: (~c_lessequals(V_B2, V_C, tc_set(T_a2)) | (~c_lessequals(V_A2, V_B2, tc_set(T_a2)) | c_lessequals(V_A2, V_C, tc_set(T_a2))))).
% 68.73/9.08 fof(cls_conjecture_0, negated_conjecture, c_lessequals(v_G, c_Message_Oanalz(v_G_H), tc_set(tc_Message_Omsg))).
% 68.73/9.08 fof(cls_conjecture_1, negated_conjecture, c_lessequals(v_H, c_Message_Oanalz(v_H_H), tc_set(tc_Message_Omsg))).
% 68.73/9.08 fof(cls_conjecture_2, negated_conjecture, ~c_lessequals(v_H, c_Message_Oanalz(c_union(v_G_H, v_H_H, tc_Message_Omsg)), tc_set(tc_Message_Omsg)) | ~c_lessequals(v_G, c_Message_Oanalz(c_union(v_G_H, v_H_H, tc_Message_Omsg)), tc_set(tc_Message_Omsg))).
% 68.73/9.08
% 68.73/9.08 Now clausify the problem and encode Horn clauses using encoding 3 of
% 68.73/9.08 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 68.73/9.08 We repeatedly replace C & s=t => u=v by the two clauses:
% 68.73/9.08 fresh(y, y, x1...xn) = u
% 68.73/9.08 C => fresh(s, t, x1...xn) = v
% 68.73/9.08 where fresh is a fresh function symbol and x1..xn are the free
% 68.73/9.08 variables of u and v.
% 68.73/9.08 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 68.73/9.08 input problem has no model of domain size 1).
% 68.73/9.08
% 68.73/9.08 The encoding turns the above axioms into the following unit equations and goals:
% 68.73/9.08
% 68.73/9.08 Axiom 1 (cls_Message_Oanalz__mono_0): fresh1091(X, X, Y, Z) = true2.
% 68.73/9.08 Axiom 2 (cls_Set_Osubset__trans_0): fresh994(X, X, Y, Z, W) = true2.
% 68.73/9.08 Axiom 3 (cls_conjecture_0): c_lessequals(v_G, c_Message_Oanalz(v_G_H), tc_set(tc_Message_Omsg)) = true2.
% 68.73/9.08 Axiom 4 (cls_conjecture_1): c_lessequals(v_H, c_Message_Oanalz(v_H_H), tc_set(tc_Message_Omsg)) = true2.
% 68.73/9.08 Axiom 5 (cls_Set_Osubset__trans_0): fresh995(X, X, Y, Z, W, V) = c_lessequals(V, Z, tc_set(W)).
% 68.73/9.08 Axiom 6 (cls_Set_OUn__upper1_0): c_lessequals(X, c_union(X, Y, Z), tc_set(Z)) = true2.
% 68.73/9.08 Axiom 7 (cls_Set_OUn__upper2_0): c_lessequals(X, c_union(Y, X, Z), tc_set(Z)) = true2.
% 68.73/9.08 Axiom 8 (cls_Message_Oanalz__mono_0): fresh1091(c_lessequals(X, Y, tc_set(tc_Message_Omsg)), true2, X, Y) = c_lessequals(c_Message_Oanalz(X), c_Message_Oanalz(Y), tc_set(tc_Message_Omsg)).
% 68.73/9.09 Axiom 9 (cls_Set_Osubset__trans_0): fresh995(c_lessequals(X, Y, tc_set(Z)), true2, Y, W, Z, X) = fresh994(c_lessequals(Y, W, tc_set(Z)), true2, W, Z, X).
% 68.73/9.09
% 68.73/9.09 Goal 1 (cls_conjecture_2): tuple(c_lessequals(v_G, c_Message_Oanalz(c_union(v_G_H, v_H_H, tc_Message_Omsg)), tc_set(tc_Message_Omsg)), c_lessequals(v_H, c_Message_Oanalz(c_union(v_G_H, v_H_H, tc_Message_Omsg)), tc_set(tc_Message_Omsg))) = tuple(true2, true2).
