% 2.19/0.68
% 2.19/0.68 % SZS output start Proof
% 2.19/0.68 Take the following subset of the input axioms:
% 2.19/0.69 fof(gauss_array_0012, conjecture, (leq(tptp_float_0_001, pv1341) & (leq(n1, loopcounter) & ((~leq(tptp_float_0_001, pv1341) => leq(n0, s_best7)) & ((~leq(tptp_float_0_001, pv1341) => leq(n0, s_sworst7)) & ((~leq(tptp_float_0_001, pv1341) => leq(n0, s_worst7)) & ((~leq(tptp_float_0_001, pv1341) => leq(s_best7, n3)) & ((~leq(tptp_float_0_001, pv1341) => leq(s_sworst7, n3)) & ((~leq(tptp_float_0_001, pv1341) => leq(s_worst7, n3)) & ((gt(loopcounter, n0) => leq(n0, s_best7)) & ((gt(loopcounter, n0) => leq(n0, s_sworst7)) & ((gt(loopcounter, n0) => leq(n0, s_worst7)) & ((gt(loopcounter, n0) => leq(s_best7, n3)) & ((gt(loopcounter, n0) => leq(s_sworst7, n3)) & (gt(loopcounter, n0) => leq(s_worst7, n3))))))))))))))) => leq(s_best7, n3)).
% 2.19/0.69 fof(leq_succ_gt, axiom, ![X, Y]: (leq(succ(X), Y) => gt(Y, X))).
% 2.19/0.69 fof(successor_1, axiom, succ(n0)=n1).
% 2.19/0.69
% 2.19/0.69 Now clausify the problem and encode Horn clauses using encoding 3 of
% 2.19/0.69 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 2.19/0.69 We repeatedly replace C & s=t => u=v by the two clauses:
% 2.19/0.69 fresh(y, y, x1...xn) = u
% 2.19/0.69 C => fresh(s, t, x1...xn) = v
% 2.19/0.69 where fresh is a fresh function symbol and x1..xn are the free
% 2.19/0.69 variables of u and v.
% 2.19/0.69 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 2.19/0.69 input problem has no model of domain size 1).
% 2.19/0.69
% 2.19/0.69 The encoding turns the above axioms into the following unit equations and goals:
% 2.19/0.69
% 2.19/0.69 Axiom 1 (successor_1): succ(n0) = n1.
% 2.19/0.69 Axiom 2 (gauss_array_0012_3): leq(n1, loopcounter) = true3.
% 2.19/0.69 Axiom 3 (gauss_array_0012_11): fresh43(X, X) = true3.
% 2.19/0.69 Axiom 4 (gauss_array_0012_11): fresh43(gt(loopcounter, n0), true3) = leq(s_best7, n3).
% 2.19/0.69 Axiom 5 (leq_succ_gt): fresh31(X, X, Y, Z) = true3.
% 2.19/0.69 Axiom 6 (leq_succ_gt): fresh31(leq(succ(X), Y), true3, X, Y) = gt(Y, X).
% 2.19/0.69
% 2.19/0.69 Goal 1 (gauss_array_0012_14): leq(s_best7, n3) = true3.
% 2.19/0.69 Proof:
% 2.19/0.69 leq(s_best7, n3)
% 2.19/0.69 = { by axiom 4 (gauss_array_0012_11) R->L }
% 2.19/0.69 fresh43(gt(loopcounter, n0), true3)
% 2.19/0.69 = { by axiom 6 (leq_succ_gt) R->L }
% 2.19/0.69 fresh43(fresh31(leq(succ(n0), loopcounter), true3, n0, loopcounter), true3)
% 2.19/0.69 = { by axiom 1 (successor_1) }
% 2.19/0.69 fresh43(fresh31(leq(n1, loopcounter), true3, n0, loopcounter), true3)
% 2.19/0.69 = { by axiom 2 (gauss_array_0012_3) }
% 2.19/0.69 fresh43(fresh31(true3, true3, n0, loopcounter), true3)
% 2.19/0.69 = { by axiom 5 (leq_succ_gt) }
% 2.19/0.69 fresh43(true3, true3)
% 2.19/0.69 = { by axiom 3 (gauss_array_0012_11) }
% 2.19/0.69 true3
% 2.19/0.69 % SZS output end Proof
% 2.19/0.69
% 2.19/0.69 RESULT: Theorem (the conjecture is true).
