% 12.94/1.98
% 12.94/1.98 Now clausify the problem and encode Horn clauses using encoding 3 of
% 12.94/1.98 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 12.94/1.98 We repeatedly replace C & s=t => u=v by the two clauses:
% 12.94/1.98 fresh(y, y, x1...xn) = u
% 12.94/1.98 C => fresh(s, t, x1...xn) = v
% 12.94/1.98 where fresh is a fresh function symbol and x1..xn are the free
% 12.94/1.98 variables of u and v.
% 12.94/1.98 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 12.94/1.98 input problem has no model of domain size 1).
% 12.94/1.98
% 12.94/1.98 The encoding turns the above axioms into the following unit equations and goals:
