Detailed Description

Example of a function to be minimized which calls an external code TCode and a dataserver whith the new TMinuit2 wrapper.

This is tested for Rosenbrock function defined as follows: Rosenbrock function is dï¿½fined 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.
