For the improved two-sided projected quasi-Newton algorithms, which were presented in PartI, we prove in this paper that they are locally one-step or two-step superlinearly convergent. Numerical tests are reported thereafter. Results by solving a set of typical problems selectedfrom literature have demonstrated the extreme importance of these modifications in making Nocedal& Overton's original methon practical. Furthermore, these results show that the improved algoritnmsare very competitive in comparison with some highly praised sequential quadratic programmingmethods. 展开更多

In this paper we improve the two versions of the two-sided projected quasi-Newton method-onewas proposed by Nocedal & Overton in [1] and the other was discussed in our previous paper, byintroducing three different merit functions to make inexact one-dimensional searches. It is shown that these improved quasi-Newton algorithms have gained global convergence propertywhich is not possessed by the original two algorithms. 展开更多
