报告题目:Progressive hedging algorithm and its applications in risk averse stochastic optimization

 

报告摘要:The progressive hedging algorithm of Rockafellar and Wets for multistage stochastic programming problems could be viewed as an application of proximal point algorithm on the partial inverse operator and a two-block alternating direction method of multipliers. This correspondence brings in some useful results. In particular, it provides a new proof for the convergence of the progressive hedging algorithm with flexibility in the selection of primal and dual step lengths and it helps to develop a new progressive hedging algorithm for solving risk averse stochastic optimization problems with cross constraints.
