% 32.38/4.55 % SZS status Theorem
% 32.38/4.55
% 32.38/4.55 % SZS output start Proof
% 32.38/4.55 Take the following subset of the input axioms:
% 32.38/4.55 fof(ax1_104, axiom, mtvisible(c_tptpgeo_member5_mt) => borderson(c_georegion_l4_x56_y47, c_georegion_l4_x57_y47)).
% 32.38/4.55 fof(ax1_1123, axiom, ![SPECMT, GENLMT]: ((mtvisible(SPECMT) & genlmt(SPECMT, GENLMT)) => mtvisible(GENLMT))).
% 32.38/4.55 fof(ax1_407, axiom, genlmt(c_tptpgeo_spindlecollectormt, c_tptpgeo_member5_mt)).
% 32.38/4.55 fof(ax1_900, axiom, ![X, Y]: (borderson(X, Y) => borderson(Y, X))).
% 32.38/4.55 fof(query109, conjecture, mtvisible(c_tptpgeo_spindlecollectormt) => borderson(c_georegion_l4_x57_y47, c_georegion_l4_x56_y47)).
% 32.38/4.55
% 32.38/4.55 Now clausify the problem and encode Horn clauses using encoding 3 of
% 32.38/4.55 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 32.38/4.55 We repeatedly replace C & s=t => u=v by the two clauses:
% 32.38/4.55 fresh(y, y, x1...xn) = u
% 32.38/4.55 C => fresh(s, t, x1...xn) = v
% 32.38/4.55 where fresh is a fresh function symbol and x1..xn are the free
% 32.38/4.55 variables of u and v.
% 32.38/4.55 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 32.38/4.55 input problem has no model of domain size 1).
% 32.38/4.55
% 32.38/4.55 The encoding turns the above axioms into the following unit equations and goals:
% 32.38/4.55
% 32.38/4.55 Axiom 1 (ax1_407): genlmt(c_tptpgeo_spindlecollectormt, c_tptpgeo_member5_mt) = true2.
% 32.38/4.55 Axiom 2 (query109): mtvisible(c_tptpgeo_spindlecollectormt) = true2.
% 32.38/4.55 Axiom 3 (ax1_104): fresh778(X, X) = true2.
% 32.38/4.55 Axiom 4 (ax1_104): fresh778(mtvisible(c_tptpgeo_member5_mt), true2) = borderson(c_georegion_l4_x56_y47, c_georegion_l4_x57_y47).
% 32.38/4.55 Axiom 5 (ax1_1123): fresh680(X, X, Y) = true2.
% 32.38/4.55 Axiom 6 (ax1_1123): fresh681(X, X, Y, Z) = mtvisible(Z).
% 32.38/4.55 Axiom 7 (ax1_900): fresh93(X, X, Y, Z) = true2.
% 32.38/4.55 Axiom 8 (ax1_1123): fresh681(mtvisible(X), true2, X, Y) = fresh680(genlmt(X, Y), true2, Y).
% 32.38/4.55 Axiom 9 (ax1_900): fresh93(borderson(X, Y), true2, X, Y) = borderson(Y, X).
% 32.38/4.55
% 32.38/4.55 Goal 1 (query109_1): borderson(c_georegion_l4_x57_y47, c_georegion_l4_x56_y47) = true2.
% 32.38/4.55 Proof:
% 32.38/4.55 borderson(c_georegion_l4_x57_y47, c_georegion_l4_x56_y47)
% 32.38/4.55 = { by axiom 9 (ax1_900) R->L }
% 32.38/4.55 fresh93(borderson(c_georegion_l4_x56_y47, c_georegion_l4_x57_y47), true2, c_georegion_l4_x56_y47, c_georegion_l4_x57_y47)

% 32.38/4.55 = { by axiom 5 (ax1_1123) }
% 32.38/4.55 fresh93(fresh778(true2, true2), true2, c_georegion_l4_x56_y47, c_georegion_l4_x57_y47)
% 32.38/4.55 = { by axiom 3 (ax1_104) }
