A NONMONOTONE TRUST REGION TECHNIQUEFOR UNCONSTRAINED OPTIMIZAfIONPROBLEMS被引量：1: 《Systems Science and Mathematical Sciences》1998年第4期375-382,共8页ZHU Detong(Department of Mathematics, Shanghai Normal University, Shanghai 200234 China); Trust region methods with nonmonotone technique for unconstrained opti-mization problems are presented and analyzed. The convergence results are demonstratedfor the proposed algorithms even if the conditions are mild.; 关键词：UNCONSTRAINED OPTIMIZATION TRUST REGION NONMONOTONE TECHNIQUE conver-gence

A NEW CONJUGATE GRADIENT METHOD AND ITS GLOBAL CONVERGENCE PROPERTIES被引量：2: 《Systems Science and Mathematical Sciences》1998年第1期53-60,共8页LI Zhengfeng CHEN Jing DENG Naiyang(Division of Basic Sciences, China Agricultural University East Campus, Beijing 100083, China); This paper presents a new conjugate gradient method for unconstrained opti-mization. This method reduces to the Polak-Ribiere-Polyak method when line searches areexact. But their performances are differellt in the cas...; 关键词：CONJUGATE GRADIENT method global CONVERGENCE UNCONSTRAINED optimization line searches.
