Modified shifted variable metric algorithms for solving unconstrained minimization problems
Abstract<br /> In this paper, we propose a modified version of the shifted VM algorithms where the matrices have the form where and are symmetric positive semi definite matrices, usually , is obtained from to satisfy the shifted modified quasi-Newton condition ,we consider our new QN-condition...
