Detailed Description

Limited memory Broyden Fletcher Goldfarb Shannon minimization with simple bounds.

This class is a wrapper for converted Fortran code for performing limited memory Broyden Fletcher Goldfarb Shannon minimization with simple bounds. The algorithm minimizes a nonlinear function f(x) of n variables subject to simple bound constraints of l <= x <= u.
