Documentation

RosenBrock This is an analytical function for testing optimization algortithms. The function looks like \[ \sum_i=1}^N-1} [100.(x_i-x_i-1}^2)^2 + (1-x_i-1})^2] \]

RosenBrock currently only takes Models either double or long integer. It is mostly because I tried to avoid using templates, due to the guliness of template features in G++. Hopefully, this could be changed soon.

this class has no child classes.
