Two Randomized Mechanisms for Combinatorial Auctionsing truthful randomized mechanisms. The framework enables the construction of mechanisms with polynomially small failure probability. This is in contrast to previous mechanisms that fail with constant probability. Another appealing feature of the new framework is that bidding truthfully is a . domin作者: 間諜活動 時間: 2025-3-22 23:17
