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 . 作者: Incorruptible 時(shí)間: 2025-3-22 04:25
