Theory of Computation (TOC) Seminar

Dana Moshkovitz: Amplification and Derandomization Without Slowdown
Tuesday, September 29, 2015 - 4:15pm to 5:15pm
Abstract: We show techniques for decreasing the error probability of randomized algorithms and for converting randomized algorithms to deterministic (non-uniform) algorithms.
David Steurer: Lower bounds on the size of semidefinite programming relaxations
Tuesday, May 19, 2015 - 4:15pm to 5:15pm

Abstract: 

Shaddin Dughmi: Algorithmic Bayesian Persuasion
Wednesday, May 13, 2015 - 4:00pm to 5:00pm

Abstract:

Elad Hazan: Is Optimization Computationally Equivalent to Online Learning?
Tuesday, May 12, 2015 - 4:15pm to 5:15pm

Abstract: 

Nir Bitansky: On the Cryptographic Hardness of Finding a Nash Equilibrium
Tuesday, April 14, 2015 - 4:15pm to 5:15pm

Abstract:

Antoine Joux: A Simplified Setting for Discrete Logarithms in Small Characteristics Fin
Tuesday, April 7, 2015 - 4:00pm to 5:15pm

Abstract:  The hardness of computing discrete logarithms in finite field has served as a foundation for many public key cryptosystems. In the last two years, tremendous progress have been made in the case of small characteristic finite fields.

Shayan Gharan: Effective-Resistance-Reducing Flows, Spectrally Thin Trees and Asymmetric TSP
Tuesday, March 3, 2015 - 4:15pm to 5:15pm

Abstract: 

Vinod Vaikuntanathan: Program Obfuscation from Functional Encryption
Tuesday, February 24, 2015 - 4:15pm to 5:15pm

Abstract: Indistinguishability obfuscation is a tremendously exciting notion, powerful enough that from it, one can construct most all cryptographic objects.

Robert Kleinberg: Secretary Problems with Non-Uniform Arrival Order
Tuesday, February 17, 2015 - 4:15pm to 5:15pm
ABSTRACT:
Constantinos Daskalakis: Mechanism Design via Optimal Transport
Tuesday, April 28, 2015 - 4:15pm to 5:15pm
Abstract: I will present an optimization framework based on optimal transport theory, characterizing the structure of revenue-optimal mechanisms in single-bidder multi
