Researchers have developed a novel approach to gradient-descent-ascent (GDA) algorithms, demonstrating that GDA can converge on min-max problems by employing unconventional, time-varying, asymmetric, and periodically negative stepsize schedules. These "slingshot" stepsizes, which involve making backward progress in certain iterations, are crucial for overcoming the cycling issues that have historically plagued GDA. This method not only enables convergence on classical counterexamples but also offers fast overall convergence by leveraging the non-reversibility of gradient flow, approximating consensus optimization techniques used in training deep neural networks like GANs.
