A CHARACTERIZATION OF SELF-SCALING RANK ONE UPDATE
《Numerical Mathematics A Journal of Chinese Universities(English Series)》2002年第1期106-112,共7页Sun Linping(孙麟平) 
The Project Suppoted by the National Natural Science Foundation (40075023).
An analysis on the property of Self-Scaling Rank One Update (SSR1) is given. In view of it, we explore whether the SSR1 update without using exact line search possesses the finite termination property when it is appli...

A NEW INEXACT SEQUENTIAL QUADRATIC PROGRAMMING ALGORITHM
《Numerical Mathematics A Journal of Chinese Universities(English Series)》2002年第1期1-12,共12页Ni Qin(倪勤) 
This work was supported by the National Natural Science Foundation of China.
This paper represents an inexact sequential quadratic programming (SQP ) algorithm which can solve nonlinear programming (NLP ) problems. An inexact solution of the quadratic programming subproblem is determined by a ...

THE CONVERGENCE OF FLETCHER-REEVES ALGORITHM
《Numerical Mathematics A Journal of Chinese Universities(English Series)》2000年第2期216-221,共6页聂普炎 莫孜中 
As concrns fletcher-Reeues algorithm,Powell showed its convergence in the case of ex- act linear search.In 1985,Al-Baali proved its conver gence when a parameter b2belangs to (0,1/ 2)for inexact linear search.and an o...

ON SOME RESULTS ABOUT INEXACT LINEAR PROGRAMMING
《Numerical Mathematics A Journal of Chinese Universities(English Series)》2000年第2期175-180,共6页孙秀真 
In this paper we point out that some theorems about the inexact programming in [2]are false and give the modified statement.

CONVERGENCE OF INEXACT CONIC NEWTON METHODS
《Numerical Mathematics A Journal of Chinese Universities(English Series)》1998年第2期159-168,共10页胡蓉 盛松柏 
A conic Newton method is attractive because it converges to a local minimizzer rapidly from any sufficiently good initial guess. However, it may be expensive to solve the conic Newton equation at each iterate. In this...

ON THE GLOBAL CONVERGENCE OF CONJUGATE GRADIENT METHODS WITH INEXACT LINESEARCH
《Numerical Mathematics A Journal of Chinese Universities(English Series)》1995年第2期147-153,共7页刘光辉 韩继业 
This work is supported by the National Natural Science Foundation of China
In this paper we consider the global convergence of any conjugate gradient method of the form d1=-g1,dk+1=-gk+1+βkdk(k≥1)with any βk satisfying sume conditions,and with the strong wolfe line search conditions.Under...
