Seminar problems - and more

Problems posted, a bit fewer than last week, since nonlinear programming could take some time. 

Practicalities (which I forgot in the heat of the action both yesterday and today):

• The course needs a contact student or two.
• If the folder with old exam problems should suddenly disappear, then please let me know ASAP. It happened last semester Mathematics 2, because all too many people have write access.
• I may "run out of problems" for the seminar in one week and a half - a few of those that fit, are maybe better suited for the longer break. We might consider shuffling lectures and seminars once again.
