We present a new smaller upper bound for all the elements in the associate generalized Hessian used in the smoothing quadratic regularization (SQR) algorithm proposed by Bian and Chen (SIAM J. Optim. 23: 1718-1741, 2013). We modify the SQR algorithm by making use of the new upper bound. Numerical results show that our new upper bound improves the(More)
In this paper, we propose a new generalized penalized Fischer–Burmeister merit function, and show that the function possesses a system of favorite properties. Moreover, for the merit function, we establish the boundedness of level set under a weaker condition. We also propose a derivative-free algorithm for nonlinear complementarity problems with a(More)
