Easy distributions for combinatorial optimization problems with probabilistic constraints
We show how we can linearize probabilistic linear constraints with binary variables when all coefficients are distributed according to either N(

Tight Bounds on the Approximability of Almost-satisfiable Horn SAT and Exact Hitting Set}
We study the approximability of two natural Boolean constraint satisfaction problems: Horn satisfiability and exact hitting set. Under the Unique Games conjecture, we prove the fo...

On Optimal Single-Item Auctions
We revisit the problem of designing the profit-maximizing single-item auction, solved by Myerson in his seminal paper for the case in which bidder valuations are independently dis...
