Extending the Reach of First-Order Algorithms for Nonconvex Min-Max Problems with Cohypomonotonicity

\(\) We focus on constrained, \(L\)-smooth, nonconvex-nonconcave min-max problems either satisfying \(\rho\)-cohypomonotonicity or admitting a solution to the \(\rho\)-weakly Minty Variational Inequality (MVI), where larger values of the parameter \(\rho>0\) correspond to a greater degree of nonconvexity.┬áThese problem classes include examples in two player reinforcement learning, interaction dominant min-max problems, and certain synthetic test problems … Read more
