%description
L-BFGS (Limited-memory Broyden-Fletcher-Goldfarb-Shanno) is a quasi-Newton
method for unconstrained optimization. This method is especially efficient
on problems involving a large number of variables.

Generally, it solves a problem described as following:

  min f(x), x = (x1, x2, ..., xn)

Jorge Nocedal wrote a Fortran 77 version of this algorithm.

http://www.ece.northwestern.edu/~nocedal/lbfgs.html

And, Naoaki Okazaki rewrote it in pure C (liblbfgs).

http://www.chokkan.org/software/liblbfgs/index.html

This module is a Perl port of Naoaki Okazaki's C version.
