Probabilistic method in combinatorics and algorithmics
LV-Nr. MAT.511UF
M. Kang, P. Sprüssel
Institute of Discrete Mathematics
Winter term 2021/22

Course dates

The course comprises 13 lectures and 6 exercise sessions and takes place every Tuesday between 2:15pm and 4:00pm, and every Wednesday between 11:30am and 1:15pm. For a detailed list of dates see TUGonline.
The venue is chosen depending on the respective Corona traffic light status:

Online classes

In order to take part in the course whenever it is held online, you will need to be able to attend Webex meetings. For presenting solutions during the exercises, your device will need to have a working microphone. A webcam or a tablet (in order to write on the screen) would be a plus, but are not strictly necessary.

Points and grades

This course will be graded based both on the participation in the exercise sessions and points gained in a written exam (90 minutes) at the end of the course. There will be a makeup exam for those who missed the original exam or have not gained enough points to pass the course. For those who take part in the makeup exam, the points from that exam will replace the points from the original exam.

The exam might be held via video conference or in a lecture hall, according to the traffic light status with the same rules as described above.

Dates of the exams

Regular exam: 11 January 2022, 14:15-16:00
Makeup exam: TBA

You can bring a sheet of paper (size DIN A4) with any handwritten notes (both sides of the sheet may be used for the notes). Any other resources are prohibited at the exam.

Points gained from exercise sessions

The exercise sheets will be available about a week before the respective exercise session. You can then use an online system (a link will be provided below) to mark which exercises you solved. The deadline for marking is precisely one hour before the start of the session. After the deadline, no changes can be made. The choice of who shall present which solution in class is made by a random generator. If you mark an exercise, you need to be present at the respective exercise session.

Attention: Keep in mind that in case of an online class, you present your solution via a video conference. The optimal way would be if you have the possibility to write the solution during the presentation (e.g., using a tablet or a camera filming you writing on paper). If such methods are not available to you, prepare your written solution as a file (e.g., scan or photograph the handwritten solution) that you can then share during the exercise session while verbally explaining the solution.

Points will also be gained by presenting solutions of exercises. Everyone should present at least one exercise in order to pass.

You should present solutions in a way that enables the other participants to follow your arguments. If it becomes apparent that someone did not do an exercise they marked in the system (it is fine if the exercise has been done, but mistakes have been made), this can be penalised by scaling all points from all exercise sessions by 0.5.

Online system for marking exercises

Before you log in for the first time, enter your student ID number; the system will then automatically send a password to your student email address. The system will update the list of participants each day. If you have just registered for the course, it may take up to 24 hours until the system recognises you.
The online system is available under the following link:

Grades

The total number of points is the sum P of the points M gained by marking solved exercises in the online system, the points S for presenting solutions, and the points E from the exam. Depending on P, the grade will be



P < 16   nicht genügend (5),
16 P < 20   genügend (4),
20 P < 24   befriedigend (3),
24 P < 28   gut (2),
28 P

  sehr gut (1).

Points for the exam

Up to 20 points can be earned in the exam.

Points for solving exercises

Up to 10 points can be earned by marking exercises. For each sheet, the points awarded for marking the exercises on this sheet will be

2 x (marked exercises) / (exercises on this sheet).

Out of the six exercise sessions, the best five will be counted for the total points.

If you miss a session, you will not be awarded any points for that session. Points lost by missing several sessions cannot be compensated.

Points for presenting solutions

Depending on the quality of the solution and the presentation, between 0 and 3 points will be awarded. In case of multiple presentations of the same student in a single session, only the best presentation will be awarded with points. If a student presents N solutions during the term with an average of A points per presentation, this will be worth S = A + log2N points.
