% 30.85/4.31
% 30.85/4.31 Now clausify the problem and encode Horn clauses using encoding 3 of
% 30.85/4.31 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 30.85/4.31 We repeatedly replace C & s=t => u=v by the two clauses:
% 30.85/4.31 fresh(y, y, x1...xn) = u
% 30.85/4.31 C => fresh(s, t, x1...xn) = v
% 30.85/4.31 where fresh is a fresh function symbol and x1..xn are the free
% 30.85/4.31 variables of u and v.
% 30.85/4.31 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 30.85/4.31 input problem has no model of domain size 1).
% 30.85/4.31
% 30.85/4.31 The encoding turns the above axioms into the following unit equations and goals:
