Abstract: A new family of limited-memory variationally-derived variable metric or quasi-Newton methods for unconstrained minimization is given. The methods have quadratic termination property and use updates, invariant under linear transformations. Some encouraging numerical experience is reported.

Keywords: Variable metric methods, limited-memory methods, large-scale 0ptimization

Category 1: Nonlinear Optimization
