Input:
   [ f(h(b,c)) -> c,
     a -> h(h(h(f(a),b),h(c,c)),f(b)),

Make it flat:

Make it Complete (R^):
   [ h(!cl_2,!cl_4) = b,
     h(!cr_0,a) = h(!cl_3,a),
     h(!cr_0,a) = h(c,a),

     h(a,c) = !cl_4,
     h(!cr_3,!cl_0) = h(!cr_3,!cr_4),
     h(!cr_3,!cl_0) = a,
     a = h(!cr_3,!cr_4),
     h(b,!cr_4) = h(b,!cl_0),
     h(b,!cr_4) = !cl_2,
     !cr_4 = !cl_0,
     !cr_4 = f(b),
     !cr_3 = h(!cr_1,!cr_2),
