Homework Problems Sets:

• Here you find a sample solution of the 1st homework problem set for download.


• Here you find a sample solution of the 2nd homework problem set for download.


• Here you find a sample solution of the 3rd homework problem set for download.

Homework and Oral Examination:

• Homework problem sets are handed out every other week. Individual, handwritten solutions are to be turned in during the next tutorial session, i.e., there are 14 days to work out the solution. The homework sets that have been handed in are graded. For a successful participation it is necessary to obtain half of the maximally possible homework points in total. The final homework grade is only "pass" or "fail".


• Even though the homework solutions are individually written down and handed in by every student seperately, it is strongly encouraged to solve the homework problems in groups.


• Each student who has obtained the homework grade "pass" is eligible to participate in an individual oral examination of about 30 minutes (20 minutes minimal length, 35 minutes maximal length).


• It is necessary to sign up for the examination at the examination office.


• Possible dates for the exam to take place are listed in http://www.iaa.tu-bs.de/vbach/2025-25_SoSe/Lehre-SoSe-2025-25.html . Send an e-mail to Mrs. Stoll including your name, your student ID number (Matrikelnummer), your study programme (e.g., "Master in Data Science"), the desired date and time of the exam, and the name of the course (Modul) of the examination.
