minimax optimization plays an important role in many machine learning tasks
such as generative adversarial networks (GANs) and adversarial training.
Although recently a wide variety of optimization methods have been proposed to
solve the minimax problems, most of them ignore the distri
该研究介绍了一种与梯度下降上升（GDA）算法相结合的 “平滑” 方案，以解决非凸 - 凹最小 - 最大问题，此方案能够稳定振荡，并确保收敛到一个定值解。实验结果表明，平滑后的 GDA 算法对于 minimizing pointwise maximum of a finite collection of nonconvex functions 可以实现 O (1/ε^2) 的迭代复杂度，对于 general nonconvex-concave problems 可以实现 O (1/ε^4) 的迭代复杂度，并且将该算法扩展到多个区块的情况下。
