Now, using the fact that B; is a symmetric matrix, (23) and (24), the relation (32) can be written as Using the relation (31), we can deduce that one choice for a good approximation to yz is given by Lemma 3 Let f satisfies Assumptions A and B. For y;, defined by (34), we have Our results are reported for the following algorithms:
