Abstract

Limited-memory versions of quasi-Newton methods are efficient methods for largescale optimization problems in the Euclidean space. In particular, a quasi-Newton symmetric rank-one update used in a trust-region setting has proven to be an effective method. In this paper, we present a Riemannian version of a limited-memory symmetric rank-one trust-region method with an efficient algorithm for solving its subproblem. Global convergence is shown to follow from a known standard result and numerical experiments are compare the proposed method with other Riemannian optimization methods.
