This paper considers the inexact Barzilai-Borwein algorithm applied to saddle point problems. To this aim, we study the convergence properties of the inexact Barzilai-Borwein algorithm for symmetric positive definite linear systems. Suppose that g k and˜g k are the exact residual and its approximation of the linear system at the k-th iteration ,(More)
