Abstract：
We present several optimization models and algorithms dealing with uncertain, massive and/or structured data. Specifically, we discuss
? Distributionally Robust Optimization Models, where many problems can be efficiently solved when the associated uncertain data possess no priori distributions;
? Near-Optimal Online Linear Programming, where the constraint matrix is revealed column by column along with the objective function and a decision has to be made as soon as a variable arrives;
? Least-squares with Nonconvex Regularization, where a sparse or low-rank solution is sought;
? Alternating Direction Method of Multipliers (ADMM), where an example is given to show that the direct extension of ADMM for three-block convex minimization problems is not necessarily convergent, and possible convergent variants are proposed.
