% 0.23/0.45 Take the following subset of the input axioms:
% 0.23/0.45 fof(cls_PropLog_Odeduction_0, axiom, ![V_q, V_p, V_H, T_a]: (~c_in(V_q, c_PropLog_Othms(c_insert(V_p, V_H, tc_PropLog_Opl(T_a)), T_a), tc_PropLog_Opl(T_a)) | c_in(c_PropLog_Opl_Oop_A_N_62(V_p, V_q, T_a), c_PropLog_Othms(V_H, T_a), tc_PropLog_Opl(T_a)))).
% 0.23/0.45 fof(cls_PropLog_Othms_OH_0, axiom, ![T_a2, V_p2, V_H2]: (~c_in(V_p2, V_H2, tc_PropLog_Opl(T_a2)) | c_in(V_p2, c_PropLog_Othms(V_H2, T_a2), tc_PropLog_Opl(T_a2)))).
% 0.23/0.45 fof(cls_PropLog_Othms__notE_0, axiom, ![T_a2, V_p2, V_q2, V_H2]: (~c_in(V_p2, c_PropLog_Othms(V_H2, T_a2), tc_PropLog_Opl(T_a2)) | (~c_in(c_PropLog_Opl_Oop_A_N_62(V_p2, c_PropLog_Opl_Ofalse, T_a2), c_PropLog_Othms(V_H2, T_a2), tc_PropLog_Opl(T_a2)) | c_in(V_q2, c_PropLog_Othms(V_H2, T_a2), tc_PropLog_Opl(T_a2))))).
% 0.23/0.45 fof(cls_PropLog_Oweaken__left__insert_0, axiom, ![V_G, V_a, T_a2, V_p2]: (~c_in(V_p2, c_PropLog_Othms(V_G, T_a2), tc_PropLog_Opl(T_a2)) | c_in(V_p2, c_PropLog_Othms(c_insert(V_a, V_G, tc_PropLog_Opl(T_a2)), T_a2), tc_PropLog_Opl(T_a2)))).
% 0.23/0.45 fof(cls_Set_OinsertCI_1, axiom, ![V_x, V_B, T_a2]: c_in(V_x, c_insert(V_x, V_B, T_a2), T_a2)).
% 0.23/0.45 fof(cls_conjecture_0, negated_conjecture, c_in(c_PropLog_Opl_Oop_A_N_62(v_p, c_PropLog_Opl_Ofalse, t_a), c_PropLog_Othms(v_H, t_a), tc_PropLog_Opl(t_a))).
% 0.23/0.45 fof(cls_conjecture_1, negated_conjecture, ~c_in(c_PropLog_Opl_Oop_A_N_62(v_p, v_q, t_a), c_PropLog_Othms(v_H, t_a), tc_PropLog_Opl(t_a))).
% 0.23/0.45
% 0.23/0.45 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.23/0.45 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.23/0.45 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.23/0.46 fresh(y, y, x1...xn) = u
% 0.23/0.46 C => fresh(s, t, x1...xn) = v
% 0.23/0.46 where fresh is a fresh function symbol and x1..xn are the free
% 0.23/0.46 variables of u and v.
% 0.23/0.46 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.23/0.46 input problem has no model of domain size 1).
% 0.23/0.46
% 0.23/0.46 The encoding turns the above axioms into the following unit equations and goals:
% 0.23/0.46
% 0.23/0.46 Axiom 1 (cls_PropLog_Othms_OH_0): fresh5(X, X, Y, Z, W) = true.
% 0.23/0.46 Axiom 2 (cls_PropLog_Othms__notE_0): fresh2(X, X, Y, Z, W) = true.
% 0.23/0.46 Axiom 3 (cls_PropLog_Oweaken__left__insert_0): fresh(X, X, Y, Z, W, V) = true.
% 0.23/0.46 Axiom 4 (cls_PropLog_Odeduction_0): fresh4(X, X, Y, Z, W, V) = true.
% 0.23/0.46 Axiom 5 (cls_Set_OinsertCI_1): c_in(X, c_insert(X, Y, Z), Z) = true.
% 0.23/0.46 Axiom 6 (cls_PropLog_Othms__notE_0): fresh3(X, X, Y, Z, W, V) = c_in(V, c_PropLog_Othms(Z, W), tc_PropLog_Opl(W)).
% 0.23/0.46 Axiom 7 (cls_PropLog_Othms_OH_0): fresh5(c_in(X, Y, tc_PropLog_Opl(Z)), true, X, Y, Z) = c_in(X, c_PropLog_Othms(Y, Z), tc_PropLog_Opl(Z)).
% 0.23/0.46 Axiom 8 (cls_conjecture_0): c_in(c_PropLog_Opl_Oop_A_N_62(v_p, c_PropLog_Opl_Ofalse, t_a), c_PropLog_Othms(v_H, t_a), tc_PropLog_Opl(t_a)) = true.
% 0.23/0.46 Axiom 9 (cls_PropLog_Oweaken__left__insert_0): fresh(c_in(X, c_PropLog_Othms(Y, Z), tc_PropLog_Opl(Z)), true, X, Y, Z, W) = c_in(X, c_PropLog_Othms(c_insert(W, Y, tc_PropLog_Opl(Z)), Z), tc_PropLog_Opl(Z)).
% 0.23/0.46 Axiom 10 (cls_PropLog_Othms__notE_0): fresh3(c_in(c_PropLog_Opl_Oop_A_N_62(X, c_PropLog_Opl_Ofalse, Y), c_PropLog_Othms(Z, Y), tc_PropLog_Opl(Y)), true, X, Z, Y, W) = fresh2(c_in(X, c_PropLog_Othms(Z, Y), tc_PropLog_Opl(Y)), true, Z, Y, W).
% 0.23/0.46 Axiom 11 (cls_PropLog_Odeduction_0): fresh4(c_in(X, c_PropLog_Othms(c_insert(Y, Z, tc_PropLog_Opl(W)), W), tc_PropLog_Opl(W)), true, X, Y, Z, W) = c_in(c_PropLog_Opl_Oop_A_N_62(Y, X, W), c_PropLog_Othms(Z, W), tc_PropLog_Opl(W)).
% 0.23/0.46
% 0.23/0.46 Goal 1 (cls_conjecture_1): c_in(c_PropLog_Opl_Oop_A_N_62(v_p, v_q, t_a), c_PropLog_Othms(v_H, t_a), tc_PropLog_Opl(t_a)) = true.
