% 27.25/3.83  
% 27.25/3.83  Now clausify the problem and encode Horn clauses using encoding 3 of
% 27.25/3.83  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 27.25/3.83  We repeatedly replace C & s=t => u=v by the two clauses:
% 27.25/3.83    fresh(y, y, x1...xn) = u
% 27.25/3.83    C => fresh(s, t, x1...xn) = v
% 27.25/3.83  where fresh is a fresh function symbol and x1..xn are the free
% 27.25/3.83  variables of u and v.
% 27.25/3.83  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 27.25/3.83  input problem has no model of domain size 1).
% 27.25/3.83  
% 27.25/3.83  The encoding turns the above axioms into the following unit equations and goals:
