    99== Solution of Almost Separable Problems with Few Common Variables ==
    1010Submitted by Carl Laird, Co-author of Ipopt 3.0.0.

    1112There 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 object-oriented optimization tool that could be easily modified for the solution of large structured problems.

    1719A joint project has been started to develop open-source solvers for mixed integer nonlinear programs (MINLPs). Ipopt 3.0 is the primary NLP solver currently used in this development.
