% 0.21/0.40 Take the following subset of the input axioms:
% 0.21/0.40 fof(cls_Event_Oc_A_58_Aparts_A_Iknows_ASpy_Aevs1_J_A_61_61_62_Ac_A_58_Aused_Aevs1_0, axiom, ![V_c, V_evs]: (~c_in(V_c, c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, V_evs)), tc_Message_Omsg) | c_in(V_c, c_Event_Oused(V_evs), tc_Message_Omsg))).
% 0.21/0.40 fof(cls_Message_OMPair__parts_0, axiom, ![V_X, V_Y, V_H]: (~c_in(c_Message_Omsg_OMPair(V_X, V_Y), c_Message_Oparts(V_H), tc_Message_Omsg) | c_in(V_Y, c_Message_Oparts(V_H), tc_Message_Omsg))).
% 0.21/0.40 fof(cls_Message_OMPair__parts_1, axiom, ![V_X2, V_H2, V_Y2]: (~c_in(c_Message_Omsg_OMPair(V_X2, V_Y2), c_Message_Oparts(V_H2), tc_Message_Omsg) | c_in(V_X2, c_Message_Oparts(V_H2), tc_Message_Omsg))).
% 0.21/0.40 fof(cls_Message_Oparts_OBody__dest_0, axiom, ![V_K, V_X2, V_H2]: (~c_in(c_Message_Omsg_OCrypt(V_K, V_X2), c_Message_Oparts(V_H2), tc_Message_Omsg) | c_in(V_X2, c_Message_Oparts(V_H2), tc_Message_Omsg))).
% 0.21/0.40 fof(cls_conjecture_2, negated_conjecture, ~c_in(c_Message_Omsg_ONonce(v_NAa), c_Event_Oused(v_evs1), tc_Message_Omsg)).
% 0.21/0.40 fof(cls_conjecture_4, negated_conjecture, v_NA=c_Message_Omsg_ONonce(v_NAa)).
% 0.21/0.40 fof(cls_conjecture_7, negated_conjecture, c_in(c_Message_Omsg_OCrypt(c_Public_OshrK(v_Aa), c_Message_Omsg_OMPair(v_NA_H, c_Message_Omsg_OMPair(c_Message_Omsg_ONonce(v_NAa), c_Message_Omsg_OMPair(c_Message_Omsg_OAgent(v_A_H), c_Message_Omsg_OAgent(v_Aa))))), c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, v_evs1)), tc_Message_Omsg)).
% 0.21/0.40
% 0.21/0.40 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.21/0.40 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.21/0.40 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.21/0.40 fresh(y, y, x1...xn) = u
% 0.21/0.40 C => fresh(s, t, x1...xn) = v
% 0.21/0.40 where fresh is a fresh function symbol and x1..xn are the free
% 0.21/0.40 variables of u and v.
% 0.21/0.40 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.21/0.40 input problem has no model of domain size 1).
% 0.21/0.40
% 0.21/0.40 The encoding turns the above axioms into the following unit equations and goals:
% 0.21/0.40
% 0.21/0.40 Axiom 1 (cls_conjecture_4): v_NA = c_Message_Omsg_ONonce(v_NAa).
% 0.21/0.40 Axiom 2 (cls_Message_Oparts_OBody__dest_0): fresh(X, X, Y, Z) = true.
% 0.21/0.40 Axiom 3 (cls_Message_OMPair__parts_0): fresh4(X, X, Y, Z) = true.
% 0.21/0.40 Axiom 4 (cls_Event_Oc_A_58_Aparts_A_Iknows_ASpy_Aevs1_J_A_61_61_62_Ac_A_58_Aused_Aevs1_0): fresh3(X, X, Y, Z) = true.
% 0.21/0.40 Axiom 5 (cls_Message_OMPair__parts_1): fresh2(X, X, Y, Z) = true.

% 0.21/0.40 Axiom 7 (cls_Message_OMPair__parts_0): fresh4(c_in(c_Message_Omsg_OMPair(X, Y), c_Message_Oparts(Z), tc_Message_Omsg), true, Y, Z) = c_in(Y, c_Message_Oparts(Z), tc_Message_Omsg).
% 0.21/0.40 Axiom 8 (cls_Event_Oc_A_58_Aparts_A_Iknows_ASpy_Aevs1_J_A_61_61_62_Ac_A_58_Aused_Aevs1_0): fresh3(c_in(X, c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, Y)), tc_Message_Omsg), true, X, Y) = c_in(X, c_Event_Oused(Y), tc_Message_Omsg).
% 0.21/0.40 Axiom 9 (cls_Message_OMPair__parts_1): fresh2(c_in(c_Message_Omsg_OMPair(X, Y), c_Message_Oparts(Z), tc_Message_Omsg), true, X, Z) = c_in(X, c_Message_Oparts(Z), tc_Message_Omsg).
% 0.21/0.40 Axiom 10 (cls_conjecture_7): c_in(c_Message_Omsg_OCrypt(c_Public_OshrK(v_Aa), c_Message_Omsg_OMPair(v_NA_H, c_Message_Omsg_OMPair(c_Message_Omsg_ONonce(v_NAa), c_Message_Omsg_OMPair(c_Message_Omsg_OAgent(v_A_H), c_Message_Omsg_OAgent(v_Aa))))), c_Message_Oparts(c_Event_Oknows(c_Message_Oagent_OSpy, v_evs1)), tc_Message_Omsg) = true.
