摘要:

我们证明了随机外推和坐标下降的原始对偶法(PURE-CD)的复杂性界,该算法已被证明在求解具有双线性耦合的凸-凹Min-Max问题时具有良好的实际性能。我们的复杂性界限匹配或改善文献中最知名的结果,密集和稀疏(强)凸(强)凹问题。

英文摘要:

We prove complexity bounds for the primal-dual algorithm with random extrapolation and coordinate descent (PURE-CD), which has been shown to obtain good practical performance for solving convex-concave min-max problems with bilinear coupling. Our complexity bounds either match or improve the best-known results in the literature for both dense and sparse (strongly)-convex-(strongly)-concave problems.
