I have updated the slides 18 -- 20 that is, those that I presented a second time at the beginning of the second hour, to address the comments I have received. If this is still unclear, please talk to the assistants tomorrow during the exercise session.
Also:
- added a slide 21 to explain how the derivatives were obtained.
- added some details on slide 10 of the optimization slides to clarify the behavior of second order methods.
