Seminar SS2021

Current Topics in Online Algorithms

Online banner


In online algorithms you have to make decisions while only seeing parts of the inputs. An example is the paging problem: If the cache is full, which page should I discard? There are different ways to judge how good an online algorithm is. We will look at new exciting developments of the last years.

Date and Time

The seminar will be held on a weekly basis. At the current time we expect the seminar to be held in online meetings. We expect you to actively participate during the presentations, e.g. asking many questions or activate the camera.

The date of the kickoff-meeting will be announced before the start of the summer semester. The regular date and time will be announced after the topics are distributed.
