Robert Gaunt,J. J. Chart,A. A. Renziarak, Raghavendra, and Steurer on using Lasserre Hierarchy for unique games. The algorithm can also be used to show that known integrality gap instances for SDP relaxations like . cannot survive a few rounds of Lasserre lifting, which also seems reason for optimism..For . graphs of diameter Δ, we ca

The second mechanism is the probabilistic serial (PS) mechanism of Bogomolnaia and Moulin [8], which computes a fractional allocation that can be expressed as a convex combination of integral allocations. The welfare factor of a mechanism is the infimum over all instances. For RSD,

https://doi.org/10.1007/BFb0116990 We give a new primal-dual algorithm and a strengthened analysis that proves a so-called Lagrangian-preserving performance guarantee. In contrast to the results of Jain & Vazirani for the uncapacitated facility location and .-median problems, our results have the surprising property that our perform
