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
*********************************
Dynamic stochastic programs in scenario tree formulation induce hierarchical sparse structures in the KKT systems of interior methods. Special factorization algorithms can exploit both the tree-dependent block sparsity and the model-specific sub-block sparsity. We propose an approach using automatically generated source code that implements sparse data structures and linear algebra operations for such factorizations. First experience with financial and other
applications will be presented.
