% 11.93/1.91  
% 11.93/1.91  Now clausify the problem and encode Horn clauses using encoding 3 of
% 11.93/1.91  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 11.93/1.91  We repeatedly replace C & s=t => u=v by the two clauses:
% 11.93/1.91    fresh(y, y, x1...xn) = u
% 11.93/1.91    C => fresh(s, t, x1...xn) = v
% 11.93/1.91  where fresh is a fresh function symbol and x1..xn are the free
% 11.93/1.91  variables of u and v.
% 11.93/1.91  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 11.93/1.91  input problem has no model of domain size 1).
% 11.93/1.91  
% 11.93/1.91  The encoding turns the above axioms into the following unit equations and goals:
