% 0.21/0.64 Take the following subset of the input axioms:

% 0.21/0.64 fof(composition_identity, axiom, ![X0_2]: composition(X0_2, one)=X0_2).
% 0.21/0.64 fof(converse_additivity, axiom, ![X0_2, X1_2]: converse(join(X0_2, X1_2))=join(converse(X0_2), converse(X1_2))).
% 0.21/0.64 fof(converse_cancellativity, axiom, ![X0_2, X1_2]: join(composition(converse(X0_2), complement(composition(X0_2, X1_2))), complement(X1_2))=complement(X1_2)).
% 0.21/0.64 fof(converse_idempotence, axiom, ![X0_2]: converse(converse(X0_2))=X0_2).
% 0.21/0.64 fof(converse_multiplicativity, axiom, ![X0_2, X1_2]: converse(composition(X0_2, X1_2))=composition(converse(X1_2), converse(X0_2))).
% 0.21/0.64 fof(def_top, axiom, ![X0_2]: top=join(X0_2, complement(X0_2))).
% 0.21/0.64 fof(def_zero, axiom, ![X0_2]: zero=meet(X0_2, complement(X0_2))).
% 0.21/0.64 fof(goals, conjecture, ![X0_2]: (join(complement(composition(X0_2, top)), composition(complement(composition(X0_2, top)), top))=composition(complement(composition(X0_2, top)), top) & join(composition(complement(composition(X0_2, top)), top), complement(composition(X0_2, top)))=complement(composition(X0_2, top)))).

% 0.21/0.64
% 0.21/0.64 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.21/0.64 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.21/0.64 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.21/0.64 fresh(y, y, x1...xn) = u
% 0.21/0.64 C => fresh(s, t, x1...xn) = v
% 0.21/0.64 where fresh is a fresh function symbol and x1..xn are the free
% 0.21/0.64 variables of u and v.
% 0.21/0.64 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.21/0.64 input problem has no model of domain size 1).
% 0.21/0.64
% 0.21/0.64 The encoding turns the above axioms into the following unit equations and goals:
% 0.21/0.64
% 0.21/0.64 Axiom 1 (composition_identity): composition(X, one) = X.
% 0.21/0.64 Axiom 2 (maddux1_join_commutativity): join(X, Y) = join(Y, X).
% 0.21/0.64 Axiom 3 (converse_idempotence): converse(converse(X)) = X.
% 0.21/0.64 Axiom 4 (def_top): top = join(X, complement(X)).
% 0.21/0.64 Axiom 5 (def_zero): zero = meet(X, complement(X)).
% 0.21/0.64 Axiom 6 (converse_multiplicativity): converse(composition(X, Y)) = composition(converse(Y), converse(X)).
% 0.21/0.64 Axiom 7 (composition_associativity): composition(X, composition(Y, Z)) = composition(composition(X, Y), Z).
% 0.21/0.64 Axiom 8 (converse_additivity): converse(join(X, Y)) = join(converse(X), converse(Y)).
% 0.21/0.64 Axiom 9 (maddux2_join_associativity): join(X, join(Y, Z)) = join(join(X, Y), Z).
% 0.21/0.64 Axiom 10 (maddux4_definiton_of_meet): meet(X, Y) = complement(join(complement(X), complement(Y))).
% 0.21/0.64 Axiom 11 (composition_distributivity): composition(join(X, Y), Z) = join(composition(X, Z), composition(Y, Z)).
% 0.21/0.64 Axiom 12 (converse_cancellativity): join(composition(converse(X), complement(composition(X, Y))), complement(Y)) = complement(Y).
% 0.21/0.64 Axiom 13 (maddux3_a_kind_of_de_Morgan): X = join(complement(join(complement(X), complement(Y))), complement(join(complement(X), Y))).
