The goal of these lectures is to acquaint the audience with a class of nasty optimization problems involving nonconvex nonlinear extendedvalued functions. Such functions arise often in multidisciplinary optimization (MDO). The context for applying our algorithms determines the form of the algorithms, and to present this context requires a bit more than just a short list of assumptions. Briefly though, the objective function and constraints depend not only on the optimization variables, but also on some ancillary variables such as the solutions of some coupled systems of standalone solvers for partial differential equations, table lookups, and other nonsmooth simulation codes. This has important algorithmic implications: First, the function and constraint values may be very expensive. Second, the functions may be nondifferentiable and discontinuous. In fact, they are often treated as extended valued since a function call may not return a value even if all the specified constraints are satisfied.
The approach we take in these lectures has been successful for some real problems in engineering design. We hope to convince engineers and mathematicians alike that not only are the algorithms given here useful, but the mathematics involved is interesting and relevant. We hope to convince mathematicians that good applied problems produce good mathematics, and that contrary to what they may have heard, they will suffer no loss of virtue as a direct result of considering them.

Breakdown of the 4 Lectures: (slides)
Lecture 1. MDO: Multidisciplinary Optimization is a contextual framework in which to view a large class of important optimization applications. MDO is the name used in aerospace but this class of problems is also called "optimization of linked subsystems" in the DOE community, and "systems of systems" in the military operations research community. This lecture will present a context in which to view various MDO formulations, including the one we will concentrate on in this shortcourse.
Lectures 2&3. Direct Search Methods: These two lectures will present algorithms and some analysis for an important subclass of MDO problems that arise in engineering design. The particular format presented allows the use of surrogates to lessen the number of expensive simulation calls needed to drive the optimization. This format will be used for algorithms with simple linear constraints, nonlinear constraints, and categorical variables. In addition, ways will be given to use poor derivative information to increase efficiency, when that information is available.
Lecture 4. Surrogate Optimization: This lecture will show how the algorithmic framework presented in the previous two lectures gives rise to the surrogate management framework. Numerical results will be given the surrogate management framework applied to some industrial design problems.
