        摘要：In this talk we discuss randomized block coordinate gradient (RBCG) methods for minimizing the sum of two functions in which one of them is block separable. In particular, we present new iteration complexity results for these methods when applied to convex optimization problems. We also propose nonmonotone RBCG methods for solving a class of nonconvex problems with the above structure, and establish their global convergence and iteration complexity. Finally, we present new complexity results for the accelerated RBCG method proposed by Nesterov for solving unconstrained convex optimization problems.
