报告内容简介：

In this talk, I will first introduce the problems we are interested in, including convex optimization problems, often with separable structures, mixed variational inequality problems and monotone operator inclusion problems. Optimality conditions, examples and various connections in between them will be included. Then, I will talk about proximal point algorithm, augmented Lagrangian method, ADMM, primal-dual algorithms, Douglas-Rachford and Davis-Yin operator splitting algorithms, and the consensus technique. Finally, I will introduce some recent results on frugal resolvent splitting with minimal lifting.
