There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu
*********************************
We discuss a bundle/trust-region algorithm for solving two-stage linear stochastic programming problems with recourse and its implementation on a computational grid. Grids are parallel computing platforms assembled from workstations, PCs, PC clusters, and conventional parallel computers. We discuss results obtained by using our code in conjunction with sampling techniques to solve many instances of sampled approximations with large sample sizes. We are able to obtain high-quality solutions to several benchmark problems in the literature, and to explore various properties of these problems and their solution sets.
