% 0.19/0.55 Take the following subset of the input axioms:

% 0.19/0.55 fof(clause98, negated_conjecture, wheel(skc11, skc12)).
% 0.19/0.55
% 0.19/0.55 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.19/0.55 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.19/0.55 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.19/0.55 fresh(y, y, x1...xn) = u
% 0.19/0.55 C => fresh(s, t, x1...xn) = v
% 0.19/0.55 where fresh is a fresh function symbol and x1..xn are the free
% 0.19/0.55 variables of u and v.
% 0.19/0.55 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.19/0.55 input problem has no model of domain size 1).
% 0.19/0.55
% 0.19/0.55 The encoding turns the above axioms into the following unit equations and goals:
% 0.19/0.55
% 0.19/0.55 Axiom 1 (clause98): wheel(skc11, skc12) = true2.
% 0.19/0.55 Axiom 2 (clause94): man(skc11, skc15) = true2.
% 0.19/0.55 Axiom 3 (clause67): fresh(X, X, Y, Z) = Z.
% 0.19/0.55 Axiom 4 (clause10): fresh78(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 5 (clause11): fresh75(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 6 (clause12): fresh59(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 7 (clause13): fresh56(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 8 (clause18): fresh51(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 9 (clause27): fresh41(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 10 (clause28): fresh40(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 11 (clause31): fresh36(X, X, Y, Z) = true2.
% 0.19/0.55 Axiom 12 (clause106): be(skc11, skc13, skc15, skc12) = true2.
% 0.19/0.55 Axiom 13 (clause10): fresh78(wheel(X, Y), true2, X, Y) = device(X, Y).
% 0.19/0.55 Axiom 14 (clause11): fresh75(device(X, Y), true2, X, Y) = instrumentality(X, Y).
% 0.19/0.55 Axiom 15 (clause12): fresh59(instrumentality(X, Y), true2, X, Y) = artifact(X, Y).
% 0.19/0.55 Axiom 16 (clause13): fresh56(artifact(X, Y), true2, X, Y) = object(X, Y).
% 0.19/0.56 Axiom 17 (clause18): fresh51(object(X, Y), true2, X, Y) = nonliving(X, Y).
% 0.19/0.56 Axiom 18 (clause27): fresh41(man(X, Y), true2, X, Y) = human_person(X, Y).
% 0.19/0.56 Axiom 19 (clause28): fresh40(human_person(X, Y), true2, X, Y) = organism(X, Y).
% 0.19/0.56 Axiom 20 (clause31): fresh36(organism(X, Y), true2, X, Y) = living(X, Y).
% 0.19/0.56 Axiom 21 (clause67): fresh(be(X, Y, Z, W), true2, Z, W) = Z.
% 0.19/0.56
% 0.19/0.56 Goal 1 (clause63): tuple2(nonliving(X, Y), living(X, Y)) = tuple2(true2, true2).
% 0.19/0.56 The goal is true when:
% 0.19/0.56 X = skc11
% 0.19/0.56 Y = skc15
