摘      要:

       In this talk, we present a transformed primal-dual gradient flow for a class of nonlinear smooth saddle point systems. We then derive several transformed primal-dual iterations by implicit Euler, explicit Euler, and implicit-explicit Euler discretization of the flow, and provide linear convergence even for non-strongly convex-concave cases.  We also give a clear convergence analysis with nonlinear inexact inner solvers.
