How to get this tutorial working
--------------------------------

The core of this tutorial is a code written in R, which one can run via a Jupyter wrapper.
Download the Jupyter Notebook (.ipynb file) and the original R code (.R file) from the github repository https://github.com/FilippoPagani/hybridRosenbrock. Required dependencies are explained below.


Technical notes
---------------

The following actions are required to run the tutorial, and should be performed with admin/sudo priviledges.

If not done already, install R on your machine (https://www.r-project.org/)

To run R commands via Jupyter, download the following R package: https://richpauloo.github.io/2018-05-16-Installing-the-R-kernel-in-Jupyter-Lab/. This will add the option of an R kernel along with the usual python ones.

A few libraries/packages (eg, RStan) are loaded in the first cell. They may not be included as default in the R version you installed, but can be easily added from the relative webpage (eg, https://cran.r-project.org/web/packages/rstan/vignettes/rstan.html). Please note that if you skip this step you will still be able to run most  of the Notebook (eg, the last two cells of it are the ones requiring RStan).
