BIU theory seminar 15-Mar-23, Clifford Stein

[Arnold Filtser]

Hi all, 

We will resume our theory seminar, with a first festive lecture by Clifford Stein.

The lecture will be on Wednesday at 12. 

Exact location, title, and abstract are yet to be announced.

Check out the schedule for the rest of the semester here: https://theory.cs.biu.ac.il/

See you there,

The info of the talk is attached below. 

See you tomorrow,

Title: Scheduling with Speed Predictions

Abstract: 

Algorithms with predictions is a recent framework that has been used to overcome pessimistic worst-case bounds in incomplete information settings. In the context of scheduling, very recent work has leveraged machine-learned predictions to design algorithms that achieve improved approximation ratios in settings where the processing times of the jobs are initially unknown. We study the speed-robust scheduling problem where the speeds of the machines, instead of the processing times of the jobs, are unknown and augment this problem with predictions. In this talk, we give an algorithm that simultaneously achieves, for any x < 1, a 1 + x approximation when the predictions are accurate and a 2+ 2/x approximation when the predictions are not accurate. We also study special cases and evaluate our algorithms performance as a function of the error.
