  Abstract: We study the optimization problem faced by a perfectly informed principal in a Bayesian game, who reveals information to the players about the state of nature to obtain a desirable equilibrium. This signaling problem is the natural design question motivated by uncertainty in games and has attracted much recent attention. We present almost-optimal hardness results for signaling problems in (a) Bayesian two-player zero-sum games, and (b) Bayesian network routing games. #R##N#For Bayesian zero-sum games, when the principal seeks to maximize the equilibrium utility of a player, we show that it is \nphard to obtain an FPTAS. Previous results ruled out an FPTAS assuming the hardness of the planted clique problem, which is an average-case assumption about the hardness of recovering a planted clique from an Erd\"os-R\'enyi random graph. Our hardness proof exploits duality and the equivalence of separation and optimization in a novel, unconventional way. Further, we preclude a PTAS assuming planted-clique hardness; previously, a PTAS was ruled out (assuming planted-clique hardness) only for games with quasi-polynomial-size strategy sets. Complementing these, we obtain a PTAS for a structured class of zero-sum games (where signaling is still NP-hard) when the payoff matrices obey a Lipschitz condition. #R##N#For Bayesian network routing games, wherein the principal seeks to minimize the average latency of the Nash flow, NP-hard to obtain an approximation ratio better than 4/3, even for linear latency functions. This is the optimal inapproximability result for linear latencies, since we show that full revelation achieves a 4/3-approximation for linear latencies.
