| Summary: | This paper presents a class of low memory quasi-Newton methods with standard
backtracking line search for large-scale unconstrained minimization. The methods
are derived by means of least change updating technique analogous to that for the
DFP method except that the full quasi-Newton matrix has been replaced by some
diagonal matrix. We establish convergence properties for some particular members
of the class under line search with Armijo condition. Sufficient conditions for the
methods to be superlinearly convergent are also given. Numerical results are then
presented to illustrate the usefulness of these methods in large-scale minimization. |
