Detailed Description
template<typename FunctorType>
class BFGS< FunctorType >
BFGS stands for Broyden–Fletcher–Goldfarb–Shanno (BFGS) method for solving unconstrained nonlinear optimization problems.
For further details please visit: http://en.wikipedia.org/wiki/BFGS_method The method provided here is almost similar to the one provided by GSL. It reproduces Fletcher's original algorithm in Practical Methods of Optimization algorithms : 2.6.2 and 2.6.4 and uses the same politics in GSL with cubic interpolation whenever it is possible else falls to quadratic interpolation for alpha parameter.
