We then present a new stochastic first-order method, namely the dynamic stochastic approximation (DSA) algorithm, for solving these types of stochastic optimization problems. In particular, we show that DSA will be efficient in solving problems with a large number of decision variables, but a relatively small number of stages. We illustrate the advantages of this method over existing ones for solving a classic multi-stage asset allocation problem.學(xué)者介紹：Guanghui (George) Lan博士畢業(yè)于佐治亞理工學(xué)院（Georgia Institute of Technology），現(xiàn)為佐治亞理工學(xué)院副教授。主要研究方向為非線性規(guī)劃、隨機(jī)優(yōu)化以及機(jī)器學(xué)習(xí)。他的研究成果在SIAM Journal on Optimization, Mathematical Programming, Journal of Computation Mathematics, Mathematical Programming等高水平期刊上發(fā)表。此外，Guanghui (George) Lan博士擔(dān)任Mathematical Programming, SIAM Journal on Optimization and Computational Optimization and Applications的副主編。
