This is tested for Rosenbrock function defined as follows: Rosenbrock function is d�fined by the equation

\[ f(x, y) \, = \, 100( y - x^{2})^{2} + ( 1 - x )^{2} \]

The minimun is reached when \( ( \star{x^{0}}, \star{y^{0}} ) \, = \, ( 1.0, 1.0 ) \)

A possible beginning point may be : \( ( x^{0}, y^{0} ) \, = \, ( -1.2, 1.0 )\) with f equal to 24.20.
