% 175.66/22.88  
% 175.66/22.88  Now clausify the problem and encode Horn clauses using encoding 3 of
% 175.66/22.88  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 175.66/22.88  We repeatedly replace C & s=t => u=v by the two clauses:
% 175.66/22.88    fresh(y, y, x1...xn) = u
% 175.66/22.88    C => fresh(s, t, x1...xn) = v
% 175.66/22.88  where fresh is a fresh function symbol and x1..xn are the free
% 175.66/22.88  variables of u and v.
% 175.66/22.88  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 175.66/22.88  input problem has no model of domain size 1).
% 175.66/22.88  
% 175.66/22.88  The encoding turns the above axioms into the following unit equations and goals:
% 175.66/22.88  
% 175.66/22.88  Axiom 1 (cls_COMBS__def_0): hAPP(hAPP(hAPP(c_COMBS(X, Y, Z), W), V), U) = hAPP(hAPP(W, U), hAPP(V, U)).
% 175.66/22.88  Axiom 2 (cls_COMBC__def_0): hAPP(hAPP(hAPP(c_COMBC(X, Y, Z), W), V), U) = hAPP(hAPP(W, U), V).
% 175.66/22.88  Axiom 3 (cls_COMBB__def_0): hAPP(hAPP(hAPP(c_COMBB(X, Y, Z), W), V), U) = hAPP(W, hAPP(V, U)).
% 175.66/22.88  
% 175.66/22.88  Goal 1 (cls_n__not__Suc__n_0): X = hAPP(c_Suc, X).
% 175.66/22.88  The goal is true when:
% 175.66/22.88    X = hAPP(hAPP(hAPP(c_COMBS(X, Y, Z), hAPP(c_COMBC(W, V, U), hAPP(c_COMBB(T, S, X2), c_Suc))), hAPP(c_COMBS(X, Y, Z), hAPP(c_COMBC(W, V, U), hAPP(c_COMBB(T, S, X2), c_Suc)))), hAPP(c_COMBS(X, Y, Z), hAPP(c_COMBC(W, V, U), hAPP(c_COMBB(T, S, X2), c_Suc))))
% 175.66/22.88
