Due to numerous requests, the submission deadline has been extended to June, 27th, 2010.

General notes and reminders:

• Don't forget to submit your solution (by email to Thomas Gabel) until June, 20th, 2010 June, 27th, 2010.
• That email must also list the names of all your team members and corresponding matriculation numbers.
• You can work in teams with up to 3 students.
• Your solution must be submitted in the form of a list with entries as follows:
  <Customer number>;<Voucher>
• The voucher field must contain a “0” for “no voucher” or a “1” for “send voucher”. The “Customer number” field must contain the entries given in file dmc2010_class.txt.
• Results that do not contain all the customer numbers from the data that is to be assessed will not be accepted.

Furthermore, you are required to present your solution in one of the the exercise sessions following the submission deadline.

• Presentation length: 15 minutes (equally distributed among team members!).
• Contents of your talk:
  • explain briefly the foundations of the methods you employed and tell the other why you decided to use those methods
  • speak about the steps you performed solving the task, including possible missteps or problems encountered
  • present the results you obtained, also using appropriate charts and diagrams.
• The schedule of the presentations will be listed on this web page after the submission deadline.
  • Hand in the slides of your presentation prior to your talk (by email to Thomas Gabel).
• Check this page frequently for any updates or changes.

Assessment of your solution: Your solution will be considered successful only, if you comply to the following five minimal requirements.

• You have submitted your solution before the submission deadline.
• You have covered all customer numbers given in dmc2010_class.txt (not just a subset) and your solution is formatted as described above.
• Your solution is not a trivial one (like, for example, sending vouchers to all customers).
• Your presentation is convincing in that it (a) shows that you have seriously dealt with the task and (b) the things you are presenting are in alignment with your submitted solution.
• You have handed in the slides of your presentation prior to your talk.
• Besides those minimal requirements (which are essential for exam qualification), we will have a course-internal DMC ranking.
  • In order to determine this ranking, the cost structure given in the task specification will be employed.
  • The best three teams will be awarded.
