0.70/0.85	Now clausify the problem and encode Horn clauses using encoding 3 of
0.70/0.85	http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
0.70/0.85	We repeatedly replace C & s=t => u=v by the two clauses:
0.70/0.85	  fresh(y, y, x1...xn) = u
0.70/0.85	  C => fresh(s, t, x1...xn) = v
0.70/0.85	where fresh is a fresh function symbol and x1..xn are the free
0.70/0.85	variables of u and v.
0.70/0.85	A predicate p(X) is encoded as p(X)=true (this is sound, because the
0.70/0.85	input problem has no model of domain size 1).
0.70/0.85	
0.70/0.85	The encoding turns the above axioms into the following unit equations and goals:
0.70/0.85	
0.70/0.85	Axiom 1 (maddux1_join_commutativity_1): join(X, Y) = join(Y, X).

0.70/0.85	Axiom 6 (maddux2_join_associativity_2): join(join(X, Y), Z) = join(X, join(Y, Z)).
0.70/0.85	Axiom 7 (converse_cancellativity_11): join(composition(converse(X), complement(composition(X, Y))), complement(Y)) = complement(Y).
0.70/0.85	Axiom 8 (def_zero_13): zero = meet(X, complement(X)).
0.70/0.85	Axiom 9 (def_top_12): join(X, complement(X)) = top.
