Algorithms and Datastructures - Conditional Course
Summer Term 2021
Fabian Kuhn
Course Description
This lecture revolves around the design and analysis of algorithms. We will discuss the concepts and principles of a selection of the very basic but most commonly used algorithms and datastructures. Topics will include for example: Sorting, searching, hashing, search-trees, (priority-)queues and graphalgorithms (like shortest paths, spanning trees breadth-first- and depth-first-searches).
Exam
- Type of exam: TBD
- Date: TBD
- Time: TBD
- Duration: TBD
- Place: TBD
- Measures due to Corona: We might offer to do the exam online via a online conference system (we will clarify that later). If the exam takes place physically, we will have a large, well ventilated room and distancing measures. Also you should bring a mask when entering the building and the seminar room (you can remove it during the exam).
Announcements
There will be an introductory session on Wednesday, 21st of April 16:15 - 18:00. The session will take place online via the conference system Zoom. Details on how to access the Zoom meeting are given below in the section Lecture Material.
Schedule
There will be a pre-recorded online lecture combined with an interactive online exercise lesson. The recurring date is Wednesday 16:15 - 18:00. If the number of participants is low, then the recurring date can be changed in agreement with all participants and the tutor. Details on how to access the Zoom meeting are given below in the section Lecture Material.
Lecture Material
All details for the weekly Zoom meeting and for Zulip are given on a seperate website. Important note: This website can only be accessed from within the university network. This can be done either by accessing the internet via the university eduroam, or by establishing a VPN tunnel to the university network. Note that you have to cancel the VPN tunnel again before you enter the Zoom meeting.
The recorded lectures will be published on the following page:

Submission of Exercises
Handing in exercises is voluntary, but we recommend doing it. If you want feedback to your solutions, you must submit them by Sunday. The submission works as follows: send an email to alkida.balliu at cs.uni-freiburg.de or dennis.olivetti at cs.uni-freiburg.de.
Solutions can be written in Latex (preferred), Word (or similar text programs) or handwritten scans. For exercises that require to write code, please also attach the python source code.
