Abstract
In this talk, Andy Sun will present some new advances in algorithm design and analysis for multistage stochastic optimization. In particular he will present a general framework of dual dynamic programming algorithms (DDP) for solving multistage stochastic mixed integer nonlinear programs and discuss an application in multistage stochastic unit commitment in electric power systems. He will also give a complexity analysis that settles an open question regarding the iteration complexity of DDP-type algorithms in this general framework. The work presented is conducted with Sun’s doctoral student, Shixuan Zhang.
