  \fbox{\parbox{0.985\linewidth}{ \small Please answer all questions
      in an electronic file (.txt, .doc are ok, but we prefer .pdf) and
      submit in ILIAS. If the assignments include programming
      exercises, hand in a pdf for the questions, the .py files for
      the programs, and the data in one zip file. 
 
      Use complete and correct sentences unless otherwise
      noted. Please be succinct. Use your own words. Write down a
      concise reasoning, not just the result.  We expect you to do
      exercises on your own, but you are encouraged to discuss the
      exercises with your fellow students. If you blindly copy your
      results from others, you miss out on a chance to learn something
      new. Use all resources available to you, but always make sure
      that you truly understand why you give the answer you give.
