% 25.84/3.62  % SZS status Theorem
% 25.84/3.62  
% 25.84/3.62  % SZS output start Proof
% 25.84/3.62  Take the following subset of the input axioms:
% 25.84/3.62    fof(ax1_322, axiom, genls(c_tptpcol_16_130924, c_tptpcol_15_130923)).
% 25.84/3.62    fof(query122, conjecture, mtvisible(f_contentmtofcdafromeventfn(f_urlreferentfn(f_urlfn(s_http_wwwarthritis_symptomcoma_cbursitishtm)), c_translation_0_885)) => genls(c_tptpcol_16_130924, c_tptpcol_15_130923)).
% 25.84/3.62  
% 25.84/3.62  Now clausify the problem and encode Horn clauses using encoding 3 of
% 25.84/3.62  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 25.84/3.62  We repeatedly replace C & s=t => u=v by the two clauses:
% 25.84/3.62    fresh(y, y, x1...xn) = u
% 25.84/3.62    C => fresh(s, t, x1...xn) = v
% 25.84/3.62  where fresh is a fresh function symbol and x1..xn are the free
% 25.84/3.62  variables of u and v.
% 25.84/3.62  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 25.84/3.62  input problem has no model of domain size 1).
% 25.84/3.62  
% 25.84/3.62  The encoding turns the above axioms into the following unit equations and goals:
% 25.84/3.62  
% 25.84/3.62  Axiom 1 (ax1_322): genls(c_tptpcol_16_130924, c_tptpcol_15_130923) = true2.
% 25.84/3.62  
% 25.84/3.62  Goal 1 (query122_1): genls(c_tptpcol_16_130924, c_tptpcol_15_130923) = true2.
% 25.84/3.62  Proof:
% 25.84/3.62    genls(c_tptpcol_16_130924, c_tptpcol_15_130923)
% 25.84/3.62  = { by axiom 1 (ax1_322) }
% 25.84/3.62    true2
% 25.84/3.62  % SZS output end Proof
% 25.84/3.62  
% 25.84/3.62  RESULT: Theorem (the conjecture is true).
