Time:
|
Wednesday, 4:15 pm to 5:45 pm
|
First meeting:
|
First Wednesday of the Summer 2015 term, i.e., 22nd April in room 023.
|
Room:
|
024 on the ground floor of the MPI building (E1.4) usually, and room 023 on Apr, 22.
|
Prerequisites:
|
You should bring a solid background in algorithms and data structures. This is an advanced seminar. The papers are challenging and a proper preparation of your talk will require some effort. Thus, you should bring a great passion for theoretical computer science.
The target audience of this reading group are master students, PhD students, as well as postdocs.
|
Content:
|
We will read (more or less) recent papers in theoretical computer science. The paper may be less recent if there is interesting follow-up work.
In each session we have a regular presentation (40-60 minutes + discussion) of one paper. Sometimes this is preceded by a short presentation of another paper (up to 20 minutes).
The reading group is open for all interested students and postdocs.
Students aiming to get credits give a regular talk and write a short summary about the paper.
|
Credits:
|
You earn the usual 7 credit points for a seminar if you (i) give a regular presentation of the paper given to you, and (ii) write a short summary (about 5 pages).
The summary should be handed in within the first two weeks after the end of the semester. You will receive comments and can improve your summary based on our comments. The presentation needs to be discussed with us at least one week before your scheduled talk in the reading group (you are supposed to give a practice talk to your supervisor).

News for students:
|
- Summaries are due on Friday, August 14th.
