[Colloquium] REMINDER: 5/26 Research at TTIC: Yury Makarychev, TTIC
Mary Marre via Colloquium
colloquium at mailman.cs.uchicago.edu
Thu May 25 10:01:00 CDT 2017
When: Friday, May 26th at noon
Where: TTIC, 6045 S Kenwood Avenue, 5th Floor, Room 526
Who: Yury Makarychev, TTIC
Title: Algorithms for Stable and Perturbation-Resilient Problems
Abstract: We study the notion of stability and perturbation resilience
introduced by Bilu and Linial (2010) and Awasthi, Blum, and Sheffet (2012).
A combinatorial optimization problem is α-stable or
α-perturbation-resilient if the optimal solution does not change when we
perturb all parameters of the problem by a factor of at most α. We present
improved algorithms for stable instances of various clustering and
optimization problems, including k-means, k-median, Max Cut, and Minimum
Multiway Cut. We also show several hardness results.
The talk is based on joint papers with Haris Angelidakis, Konstantin
Makarychev, and Aravindan Vijayaraghavan.

*Research at TTIC Seminar Series*
TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research. The lectures are intended both for students
seeking research topics and adviser, and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.
To receive announcements about the seminar series, please subscribe to the
