WebbThe general constraint-coupled set-up we consider in this paper has not received extensive investigation in a purely distributed framework and only few works are available, i.e., [26]–[30]. In [26] a consensus-based primal-dual perturbation algorithm is proposed to solve smooth constraint-coupled optimization problems. Very recently, WebbIn particular, one can distinguish between problems dealing with local and global models of robustness; and between probabilistic and non-probabilistic models of robustness. Modern robust optimization deals primarily with non-probabilistic models of robustness that are worst case oriented and as such usually deploy Wald's maximin models .

Stochastic optimization (SO) methods are optimization methods that generate and use random variables. For stochastic problems, the random variables appear in the formulation of the optimization problem itself, which involves random objective functions or random constraints. Stochastic optimization methods also include methods with random iterates. Some stochastic optimization methods use random iterates to solve stochastic problems, combining both meani… Webb9 mars 2013 · Probabilistic Constrained Optimization: Methodology and Applications Volume 49 of Nonconvex Optimization and Its Applications: Editor: Stanislav Uryasev: …
