% 25.45/3.66 % SZS status Theorem
% 25.45/3.66
% 25.45/3.66 % SZS output start Proof
% 25.45/3.66 Take the following subset of the input axioms:
% 25.45/3.67 fof(ax1_153, axiom, ![OBJ]: ~(tptpcol_1_1(OBJ) & tptpcol_1_65536(OBJ))).
% 25.45/3.67 fof(ax1_167, axiom, ![OBJ2]: ~(individual(OBJ2) & setorcollection(OBJ2))).
% 25.45/3.67 fof(ax1_289, axiom, ![OBJ2]: ~(collection(OBJ2) & individual(OBJ2))).
% 25.45/3.67 fof(ax1_3, axiom, ![OBJ2]: ~(intangible(OBJ2) & partiallytangible(OBJ2))).
% 25.45/3.67 fof(ax1_363, axiom, ![COL1, COL2, OBJ2]: ~(isa(OBJ2, COL1) & (isa(OBJ2, COL2) & disjointwith(COL1, COL2)))).
% 25.45/3.67 fof(ax1_452, axiom, mtvisible(c_englishmt) => prettystring(f_instancewithrelationtofn(c_footballteam, c_affiliatedwith, c_beloitcollege), s_thefootballteamwhohasbeenaffiliatedwithbeloitcollege)).
% 25.45/3.67 fof(ax1_488, axiom, ![OBJ2]: ~(tptpcol_3_98305(OBJ2) & tptpcol_3_114688(OBJ2))).
% 25.45/3.67 fof(ax1_521, axiom, ![X]: ~affiliatedwith(X, X)).
% 25.45/3.67 fof(ax1_698, axiom, ![X2]: ~objectfoundinlocation(X2, X2)).
% 25.45/3.67 fof(ax1_901, axiom, ![X2]: ~borderson(X2, X2)).
% 25.45/3.67 fof(query85, conjecture, ?[X2]: (mtvisible(c_englishmt) => prettystring(f_instancewithrelationtofn(c_footballteam, c_affiliatedwith, c_beloitcollege), X2))).
% 25.45/3.67
% 25.45/3.67 Now clausify the problem and encode Horn clauses using encoding 3 of
% 25.45/3.67 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 25.45/3.67 We repeatedly replace C & s=t => u=v by the two clauses:
% 25.45/3.67 fresh(y, y, x1...xn) = u
% 25.45/3.67 C => fresh(s, t, x1...xn) = v
% 25.45/3.67 where fresh is a fresh function symbol and x1..xn are the free
% 25.45/3.67 variables of u and v.
% 25.45/3.67 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 25.45/3.67 input problem has no model of domain size 1).
% 25.45/3.67
% 25.45/3.67 The encoding turns the above axioms into the following unit equations and goals:
% 25.45/3.67
% 25.45/3.67 Axiom 1 (query85): mtvisible(c_englishmt) = true2.
% 25.45/3.67 Axiom 2 (ax1_452): fresh507(X, X) = true2.
% 25.45/3.67 Axiom 3 (ax1_452): fresh507(mtvisible(c_englishmt), true2) = prettystring(f_instancewithrelationtofn(c_footballteam, c_affiliatedwith, c_beloitcollege), s_thefootballteamwhohasbeenaffiliatedwithbeloitcollege).
% 25.45/3.67
% 25.45/3.67 Goal 1 (query85_1): prettystring(f_instancewithrelationtofn(c_footballteam, c_affiliatedwith, c_beloitcollege), X) = true2.
% 25.45/3.67 The goal is true when:
% 25.45/3.67 X = s_thefootballteamwhohasbeenaffiliatedwithbeloitcollege
% 25.45/3.67
% 25.45/3.67 Proof:
% 25.45/3.67 prettystring(f_instancewithrelationtofn(c_footballteam, c_affiliatedwith, c_beloitcollege), s_thefootballteamwhohasbeenaffiliatedwithbeloitcollege)
% 25.45/3.67 = { by axiom 3 (ax1_452) R->L }
% 25.45/3.67 fresh507(mtvisible(c_englishmt), true2)
% 25.45/3.67 = { by axiom 1 (query85) }
% 25.45/3.67 fresh507(true2, true2)
% 25.45/3.67 = { by axiom 2 (ax1_452) }
% 25.45/3.67 true2
% 25.45/3.67 % SZS output end Proof
% 25.45/3.67
% 25.45/3.67 RESULT: Theorem (the conjecture is true).
