% 0.19/0.72 Take the following subset of the input axioms:
% 0.19/0.74 fof(quaternion_ds1_inuse_0017, conjecture, (a_select2(rho_defuse, n0)=use & (a_select2(rho_defuse, n1)=use & (a_select2(rho_defuse, n2)=use & (a_select2(sigma_defuse, n0)=use & (a_select2(sigma_defuse, n1)=use & (a_select2(sigma_defuse, n2)=use & (a_select2(sigma_defuse, n3)=use & (a_select2(sigma_defuse, n4)=use & (a_select2(sigma_defuse, n5)=use & (a_select3(u_defuse, n0, n0)=use & (a_select3(u_defuse, n1, n0)=use & (a_select3(u_defuse, n2, n0)=use & (a_select2(xinit_defuse, n3)=use & (a_select2(xinit_defuse, n4)=use & (a_select2(xinit_defuse, n5)=use & (a_select2(xinit_mean_defuse, n0)=use & (a_select2(xinit_mean_defuse, n1)=use & (a_select2(xinit_mean_defuse, n2)=use & (a_select2(xinit_mean_defuse, n3)=use & (a_select2(xinit_mean_defuse, n4)=use & (a_select2(xinit_mean_defuse, n5)=use & (a_select2(xinit_noise_defuse, n0)=use & (a_select2(xinit_noise_defuse, n1)=use & (a_select2(xinit_noise_defuse, n2)=use & (a_select2(xinit_noise_defuse, n3)=use & (a_select2(xinit_noise_defuse, n4)=use & (a_select2(xinit_noise_defuse, n5)=use & (![B, A2]: ((leq(n0, A2) & (leq(n0, B) & (leq(A2, n2) & leq(B, n998)))) => a_select3(u_defuse, A2, B)=use) & ![C, D]: ((leq(n0, C) & (leq(n0, D) & (leq(C, n2) & leq(D, n998)))) => a_select3(z_defuse, C, D)=use))))))))))))))))))))))))))))) => ![E, F]: ((leq(n0, E) & (leq(n0, F) & (leq(E, n2) & leq(F, n998)))) => a_select3(u_defuse, E, F)=use)).
% 0.19/0.74
% 0.19/0.74 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.19/0.74 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.19/0.74 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.19/0.74 fresh(y, y, x1...xn) = u
% 0.19/0.74 C => fresh(s, t, x1...xn) = v
% 0.19/0.74 where fresh is a fresh function symbol and x1..xn are the free
% 0.19/0.74 variables of u and v.
% 0.19/0.74 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.19/0.74 input problem has no model of domain size 1).
% 0.19/0.74
% 0.19/0.74 The encoding turns the above axioms into the following unit equations and goals:
% 0.19/0.74
% 0.19/0.74 Axiom 1 (quaternion_ds1_inuse_0017_27): leq(n0, f) = true3.
% 0.19/0.74 Axiom 2 (quaternion_ds1_inuse_0017_28): leq(n0, e) = true3.
% 0.19/0.74 Axiom 3 (quaternion_ds1_inuse_0017_29): leq(f, n998) = true3.
% 0.19/0.74 Axiom 4 (quaternion_ds1_inuse_0017_30): leq(e, n2) = true3.
% 0.19/0.74 Axiom 5 (quaternion_ds1_inuse_0017_32): fresh48(X, X, Y, Z) = use.
% 0.19/0.74 Axiom 6 (quaternion_ds1_inuse_0017_32): fresh46(X, X, Y, Z) = a_select3(u_defuse, Y, Z).
% 0.19/0.74 Axiom 7 (quaternion_ds1_inuse_0017_32): fresh47(X, X, Y, Z) = fresh48(leq(Y, n2), true3, Y, Z).
% 0.19/0.74 Axiom 8 (quaternion_ds1_inuse_0017_32): fresh45(X, X, Y, Z) = fresh46(leq(Z, n998), true3, Y, Z).
% 0.19/0.74 Axiom 9 (quaternion_ds1_inuse_0017_32): fresh45(leq(n0, X), true3, Y, X) = fresh47(leq(n0, Y), true3, Y, X).
% 0.19/0.74
% 0.19/0.74 Goal 1 (quaternion_ds1_inuse_0017_31): a_select3(u_defuse, e, f) = use.
% 0.19/0.74 Proof:
% 0.19/0.74 a_select3(u_defuse, e, f)
% 0.19/0.74 = { by axiom 6 (quaternion_ds1_inuse_0017_32) R->L }
% 0.19/0.74 fresh46(true3, true3, e, f)
% 0.19/0.74 = { by axiom 3 (quaternion_ds1_inuse_0017_29) R->L }
% 0.19/0.74 fresh46(leq(f, n998), true3, e, f)
% 0.19/0.74 = { by axiom 8 (quaternion_ds1_inuse_0017_32) R->L }
% 0.19/0.74 fresh45(true3, true3, e, f)
% 0.19/0.74 = { by axiom 1 (quaternion_ds1_inuse_0017_27) R->L }
% 0.19/0.74 fresh45(leq(n0, f), true3, e, f)
% 0.19/0.74 = { by axiom 9 (quaternion_ds1_inuse_0017_32) }
% 0.19/0.74 fresh47(leq(n0, e), true3, e, f)
% 0.19/0.74 = { by axiom 2 (quaternion_ds1_inuse_0017_28) }
% 0.19/0.74 fresh47(true3, true3, e, f)
% 0.19/0.74 = { by axiom 7 (quaternion_ds1_inuse_0017_32) }
% 0.19/0.74 fresh48(leq(e, n2), true3, e, f)
% 0.19/0.74 = { by axiom 4 (quaternion_ds1_inuse_0017_30) }
% 0.19/0.74 fresh48(true3, true3, e, f)
% 0.19/0.74 = { by axiom 5 (quaternion_ds1_inuse_0017_32) }
% 0.19/0.74 use
% 0.19/0.74 % SZS output end Proof
% 0.19/0.74
% 0.19/0.74 RESULT: Theorem (the conjecture is true).
