Inapproximability of NP-Complete Variants of Nash Equilibriumbrium is just one of several known NP-hard problems related to Nash equilibrium, all of which have approximate variants which are as hard as finding a planted clique. In particular, we show this for approximate variants of the following problems: finding a Nash equilibrium with value greater than .

Optimal Lower Bounds for Universal and Differentially Private Steiner Trees and TSPsblems admit .(log.)-approximate universal algorithms, and hence .(log.) approximate differentially private algorithms as well..We prove an Ω(log.) lower bound on the approximation ratio achievable for the universal Steiner tree problem and the universal TSP, matching the known upper bounds. Our lowe

Primal-Dual Schema and Lagrangian Relaxation for the ,-Location-Routing Problem 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
