% 0.22/0.60  % SZS status Theorem
% 0.22/0.60  
% 0.22/0.60  % SZS output start Proof
% 0.22/0.60  Take the following subset of the input axioms:
% 0.22/0.60    fof(gauss_array_0018, conjecture, ~leq(tptp_float_0_001, tptp_float_0_001) => leq(s_best7, n3)).
% 0.22/0.60    fof(reflexivity_leq, axiom, ![X]: leq(X, X)).
% 0.22/0.60  
% 0.22/0.60  Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.22/0.60  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.22/0.60  We repeatedly replace C & s=t => u=v by the two clauses:
% 0.22/0.60    fresh(y, y, x1...xn) = u
% 0.22/0.60    C => fresh(s, t, x1...xn) = v
% 0.22/0.60  where fresh is a fresh function symbol and x1..xn are the free
% 0.22/0.60  variables of u and v.
% 0.22/0.60  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.22/0.60  input problem has no model of domain size 1).
% 0.22/0.60  
% 0.22/0.60  The encoding turns the above axioms into the following unit equations and goals:
% 0.22/0.60  
% 0.22/0.60  Axiom 1 (reflexivity_leq): leq(X, X) = true3.
% 0.22/0.60  
% 0.22/0.60  Goal 1 (gauss_array_0018): leq(tptp_float_0_001, tptp_float_0_001) = true3.
% 0.22/0.60  Proof:
% 0.22/0.60    leq(tptp_float_0_001, tptp_float_0_001)
% 0.22/0.60  = { by axiom 1 (reflexivity_leq) }
% 0.22/0.60    true3
% 0.22/0.60  % SZS output end Proof
% 0.22/0.60  
% 0.22/0.60  RESULT: Theorem (the conjecture is true).
