This paper is concerned with a conjugate gradient method that utilizes a successive set of preconditioner matrices. The method is developed for the solution of min{f (x): x ∈ R n }, where f is a nonlinear function that is sufficiently smooth to possess a Hessian matrix that is continuous. The theory

## Abstract This paper is concerned with the numerical solution of a symmetric indefinite system which is a generalization of the Karush–Kuhn–Tucker system. Following the recent approach of LukΕ‘an and Vlček, we propose to solve this system by a preconditioned conjugate gradient (PCG) algorithm and
