% 1.80/0.62 % SZS output start Proof
% 1.80/0.62 Take the following subset of the input axioms:
% 2.14/0.63 fof(cl5_nebula_init_0026, conjecture, (leq(n0, pv10) & (leq(n0, pv52) & (leq(n0, pv54) & (leq(pv10, n135299) & (leq(pv52, n4) & (leq(pv54, n4) & (gt(loopcounter, n1) & (![A2]: ((leq(n0, A2) & leq(A2, n135299)) => ![B]: ((leq(n0, B) & leq(B, n4)) => a_select3(q_init, A2, B)=init)) & (![C]: ((leq(n0, C) & leq(C, n4)) => a_select2(rho_init, C)=init) & (![D]: ((leq(n0, D) & leq(D, n4)) => a_select2(mu_init, D)=init) & (![E]: ((leq(n0, E) & leq(E, n4)) => a_select2(sigma_init, E)=init) & (![F]: ((leq(n0, F) & leq(F, n4)) => a_select3(center_init, F, n0)=init) & ((gt(loopcounter, n1) => ![G]: ((leq(n0, G) & leq(G, n4)) => a_select2(muold_init, G)=init)) & ((gt(loopcounter, n1) => ![H]: ((leq(n0, H) & leq(H, n4)) => a_select2(rhoold_init, H)=init)) & (gt(loopcounter, n1) => ![I]: ((leq(n0, I) & leq(I, n4)) => a_select2(sigmaold_init, I)=init)))))))))))))))) => ![J]: ((leq(n0, J) & leq(J, n4)) => a_select2(muold_init, J)=init)).
% 2.14/0.63
% 2.14/0.63 Now clausify the problem and encode Horn clauses using encoding 3 of
% 2.14/0.63 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 2.14/0.63 We repeatedly replace C & s=t => u=v by the two clauses:
% 2.14/0.63 fresh(y, y, x1...xn) = u
% 2.14/0.63 C => fresh(s, t, x1...xn) = v
% 2.14/0.64 where fresh is a fresh function symbol and x1..xn are the free
% 2.14/0.64 variables of u and v.
% 2.14/0.64 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 2.14/0.64 input problem has no model of domain size 1).
% 2.14/0.64
% 2.14/0.64 The encoding turns the above axioms into the following unit equations and goals:
% 2.14/0.64
% 2.14/0.64 Axiom 1 (cl5_nebula_init_0026_4): leq(n0, j) = true3.
% 2.14/0.64 Axiom 2 (cl5_nebula_init_0026_8): leq(j, n4) = true3.
% 2.14/0.64 Axiom 3 (cl5_nebula_init_0026): gt(loopcounter, n1) = true3.
% 2.14/0.64 Axiom 4 (cl5_nebula_init_0026_10): fresh61(X, X, Y) = init.
% 2.14/0.64 Axiom 5 (cl5_nebula_init_0026_10): fresh51(X, X, Y) = a_select2(muold_init, Y).
% 2.14/0.64 Axiom 6 (cl5_nebula_init_0026_10): fresh60(X, X, Y) = fresh61(gt(loopcounter, n1), true3, Y).
% 2.14/0.64 Axiom 7 (cl5_nebula_init_0026_10): fresh60(leq(n0, X), true3, X) = fresh51(leq(X, n4), true3, X).
% 2.14/0.64
% 2.14/0.64 Goal 1 (cl5_nebula_init_0026_9): a_select2(muold_init, j) = init.
% 2.14/0.64 Proof:
% 2.14/0.64 a_select2(muold_init, j)
% 2.14/0.64 = { by axiom 5 (cl5_nebula_init_0026_10) R->L }
% 2.14/0.64 fresh51(true3, true3, j)
% 2.14/0.64 = { by axiom 2 (cl5_nebula_init_0026_8) R->L }
% 2.14/0.64 fresh51(leq(j, n4), true3, j)
% 2.14/0.64 = { by axiom 7 (cl5_nebula_init_0026_10) R->L }
% 2.14/0.64 fresh60(leq(n0, j), true3, j)
% 2.14/0.64 = { by axiom 1 (cl5_nebula_init_0026_4) }
% 2.14/0.64 fresh60(true3, true3, j)
% 2.14/0.64 = { by axiom 6 (cl5_nebula_init_0026_10) }
% 2.14/0.64 fresh61(gt(loopcounter, n1), true3, j)
% 2.14/0.64 = { by axiom 3 (cl5_nebula_init_0026) }
% 2.14/0.64 fresh61(true3, true3, j)
% 2.14/0.64 = { by axiom 4 (cl5_nebula_init_0026_10) }
% 2.14/0.64 init
% 2.14/0.64 % SZS output end Proof
% 2.14/0.64
% 2.14/0.64 RESULT: Theorem (the conjecture is true).
