% 0.20/0.47 % SZS output start Proof
% 0.20/0.47 Take the following subset of the input axioms:
% 0.20/0.47 fof(just11, axiom, ![ARG1, ARG2]: (tptptypes_8_400(ARG1, ARG2) => tptptypes_7_396(ARG1, ARG2))).
% 0.20/0.47 fof(just13, axiom, ![ARG1_2, ARG2_2]: (tptptypes_9_401(ARG1_2, ARG2_2) => tptptypes_8_400(ARG2_2, ARG1_2))).
% 0.20/0.47 fof(just15, axiom, genlmt(c_tptp_spindlecollectormt, c_tptp_member237_mt)).
% 0.20/0.47 fof(just18, axiom, mtvisible(c_tptp_member237_mt) => tptptypes_9_401(c_pushingababycarriage, c_tptpcol_16_10258)).
% 0.20/0.47 fof(just19, axiom, ![OBJ, COL1, COL2]: ~(isa(OBJ, COL1) & (isa(OBJ, COL2) & disjointwith(COL1, COL2)))).
% 0.20/0.47 fof(just59, axiom, ![SPECMT, GENLMT]: ((mtvisible(SPECMT) & genlmt(SPECMT, GENLMT)) => mtvisible(GENLMT))).
% 0.20/0.47 fof(just7, axiom, ![ARG1_2, ARG2_2]: (tptptypes_6_388(ARG1_2, ARG2_2) => tptptypes_5_387(ARG1_2, ARG2_2))).
% 0.20/0.47 fof(just9, axiom, ![ARG1_2, ARG2_2]: (tptptypes_7_396(ARG1_2, ARG2_2) => tptptypes_6_388(ARG1_2, ARG2_2))).
% 0.20/0.47 fof(query73, conjecture, ?[ARG1_2]: (mtvisible(c_tptp_spindlecollectormt) => tptptypes_5_387(ARG1_2, c_pushingababycarriage))).
% 0.20/0.47
% 0.20/0.47 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.20/0.47 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.20/0.47 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.20/0.47 fresh(y, y, x1...xn) = u
% 0.20/0.47 C => fresh(s, t, x1...xn) = v
% 0.20/0.47 where fresh is a fresh function symbol and x1..xn are the free
% 0.20/0.47 variables of u and v.
% 0.20/0.47 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.20/0.47 input problem has no model of domain size 1).
% 0.20/0.47
% 0.20/0.47 The encoding turns the above axioms into the following unit equations and goals:
% 0.20/0.47
% 0.20/0.47 Axiom 1 (just15): genlmt(c_tptp_spindlecollectormt, c_tptp_member237_mt) = true2.
% 0.20/0.47 Axiom 2 (query73): mtvisible(c_tptp_spindlecollectormt) = true2.
% 0.20/0.47 Axiom 3 (just18): fresh58(X, X) = true2.
% 0.20/0.47 Axiom 4 (just18): fresh58(mtvisible(c_tptp_member237_mt), true2) = tptptypes_9_401(c_pushingababycarriage, c_tptpcol_16_10258).
% 0.20/0.47 Axiom 5 (just59): fresh11(X, X, Y) = true2.
% 0.20/0.47 Axiom 6 (just9): fresh(X, X, Y, Z) = true2.
% 0.20/0.47 Axiom 7 (just13): fresh60(X, X, Y, Z) = true2.
% 0.20/0.47 Axiom 8 (just11): fresh59(X, X, Y, Z) = true2.
% 0.20/0.47 Axiom 9 (just59): fresh12(X, X, Y, Z) = mtvisible(Z).
% 0.20/0.47 Axiom 10 (just7): fresh2(X, X, Y, Z) = true2.
% 0.20/0.47 Axiom 11 (just9): fresh(tptptypes_7_396(X, Y), true2, X, Y) = tptptypes_6_388(X, Y).
% 0.20/0.47 Axiom 12 (just13): fresh60(tptptypes_9_401(X, Y), true2, X, Y) = tptptypes_8_400(Y, X).
% 0.20/0.47 Axiom 13 (just11): fresh59(tptptypes_8_400(X, Y), true2, X, Y) = tptptypes_7_396(X, Y).
% 0.20/0.47 Axiom 14 (just59): fresh12(mtvisible(X), true2, X, Y) = fresh11(genlmt(X, Y), true2, Y).
% 0.20/0.47 Axiom 15 (just7): fresh2(tptptypes_6_388(X, Y), true2, X, Y) = tptptypes_5_387(X, Y).
% 0.20/0.47
% 0.20/0.47 Goal 1 (query73_1): tptptypes_5_387(X, c_pushingababycarriage) = true2.
% 0.20/0.47 The goal is true when:
% 0.20/0.47 X = c_tptpcol_16_10258
% 0.20/0.47
