Wednesday 11:00-13:00 (SP G2.02)
Friday 11:00-13:00 (SP F2.04)
The first lecture is on Friday February 9 at 11:00 in room SP F2.04.
(There are a few exceptions. See the entries marked in red in the schedule below.)
Friday 15:00-17:00 (SP G0.05)
Computational Complexity: A Modern Approach, by Sanjeev Arora and Boaz Barak.
Homework exercises will generally be handed out on Wednesday and have to be handed in on Wednesday one week later. Handing in via email to Jan Czajkowski is encouraged. You are allowed to cooperate, but everyone has to write down their solution in their own words. When computing the average grade for the exercises, the lowest score will be dropped.
Besides the exercises there will be a final exam. The exam will be open book, which means you are allowed to bring the book and any notes you made – digital equipment is not allowed. The final grade for the course will be the average of the grade for the exercises and the final exam.
(Entries marked in red are lectures that are exceptions to the regular days/locations.)
