The discrepancy between the minimax and maximin objective values could serve as a proxy for the difficulties that the alternating gradient descent encounters in the optimization of GANs. In this work, we give new results on the benefits of multi-generator architecture of GANs. We show that the minimax gap shrinks to $\\epsilon$ as the number of generators increases with rate $\\widetilde{O}(1/\\epsilon)$. This improves over the best-known result of $\\widetilde{O}(1/\\epsilon^2)$.
