Augmented Lagrangian method within L-shaped method for stochastic linear programs

摘要

Stochastic programming is an optimization technique used in the presence of uncertainty and it typically leads to very large problem sizes. In this paper, a modified version of the L-shaped method was used to solve two-stage stochastic linear programs with recourse, based on the projection method and the augmented Lagrangian method. Using this modified version of the L-shaped method allows us to reduce the number of iterations and the time of solving a two-stage stochastic linear program with fixed recourse, in comparison with traditional methods.
