|
Credit Points: | 8CP for Informatik Bachelor and Mathematik Bachelor (252-0209-00L, 4V + 2U + 1A) |
Language: | English |
Contents: |
Advanced design and analysis methods for algorithms and data structures.
Preliminary list of topics:
|
Literature: |
Reading assignments are Basics of Probabilistic Analysis for the APC-Lecture. Detailed lecture notes will be sold in the lecture. The following textbooks do not cover all topics of the course (neither is every topic treated in these textbooks a topic of the course).
|
Prerequisites: | Basic knowledge of Probability Theory and Theoretical Computer Science as provided by the lectures Probability and Statistics and Theoretical Computer Science of the Bachelor Programme. |
There will be a written midterm exam and a written final exam. Furthermore, there will be two mandatory special assignments (SPAs), the solution of which is due two weeks later. Your solution should be typeset in LaTeX.
The final grade of the whole course will be calculated as a weighted average of the grades for the final exam (60%), midterm exam (20%), and the special assignments (20%).
Oct 10 – Oct 24 at 2:15 pm. | |
Midterm Exam: |
On Monday, 30 October 2017, instead of the
lecture (13:00-15:00) and at the Hönggerberg campus. No written material will be permitted. The exam covers all material up to the lecture on October 24. You may find previous midterms here: 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015. 2016. |
Special assignment 2 (Minor update on 22.11.): |
Nov 21 – Dec 5. |
Final exam: | Feb 10, 2018 You may find previous finals here: 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016. |
Absence. If there are compelling reasons why you cannot attend the midterm or hand in a special assignment on the due date foreseen, please contact us post-haste and we can look for a solution. Note, however, that we will grant requests of this type only in very exceptional cases (doctor's note, military service, funeral, etc.). Private events (vacation, sports, career fairs, etc.) are never sufficient grounds. As far as special assignments are concerned, you can hand them in to the contact assistant by email at any time before the due date, so there is no need to be present in person. As regards the final exam, ETH regulations apply.
Exchange students. Exchange students enrolled for APC in fall might want to return to their home university prior to the date of the final exam. If this applies to you and you nonetheless wish to be evaluated and given credits for APC, then as an alternative to returning to Zurich for the exam, there is the possibility for you to take the exam at your home university at the same time it takes place in Zurich. If you want to make use of this exam mode, you as a student are responsible for finding a professor at your home university who is willing to allocate resources for such a supervision and for establishing contact between us and the other party. At any rate, arrangements of this type have to be made very timely, preferably at the beginning of the semester. If you contact us too late, we cannot help you.
Regular exercises are made available online on a weekly basis. Students are expected to (try and) solve the problems and attend the exercise classes. Your assistant is happy to look at your solutions and correct/comment them. All exercises and their solutions are part of the material relevant for the two exams.
In the table below you can find the lecture dates and the preliminary topics. The exercises and their solutions will be published here.
