v2 v3 9 9 == Solution of Almost Separable Problems with Few Common Variables == 10 10 Submitted by Carl Laird, Coauthor of Ipopt 3.0.0. 11 11 12 There are a number of optimization problems that can be cast into a form that has an almost separable structure with few common variables (Optimal Design Under Uncertainty). The linear system that is solved at each iteration of Ipopt inherits this problem structure and decomposition techniques exist for efficient solution of these large NLPs. My primary interest in contributing to the new C++ version of Ipopt was to help build an objectoriented optimization tool that could be easily modified for the solution of large structured problems. 12 13 … … 15 16 == Solution of Mixed Integer Nonlinear Programs == 16 17 Ongoing research project involving IBM and Carnegie Mellon University. 18 17 19 A joint project has been started to develop opensource solvers for mixed integer nonlinear programs (MINLPs). Ipopt 3.0 is the primary NLP solver currently used in this development. To see more details about this project, see [http://egon.cheme.cmu.edu/IBM/page.htm CMUIBM Open Source MINLP Project]
