Optimization problems arise in multiple areas of science, engineering and business. This course introduces numerical methods for continuous optimization, focusing on practical methods. The course will cover derivative-based methods for constrained and unconstrained multivariate optimization, including line-search and trust-region strategies; conjugate-gradient, Newton and quasi-Newton methods; linear programming (simplex and interior-point methods); quadratic programming; penalty, barrier and augmented Lagrangian methods; and sequential quadratic programming. The primary programming tool for this course is Matlab.
Prerequisites: undergraduate courses in linear algebra and multivariate calculus. Basic concepts will be briefly reviewed during the course.

One third each of these:
- Homework: exercises (mainly from the textbook) of two types, pencil-and-paper and Matlab programming. For programming exercises, email me a .tar.gz or .zip file containing your code (which should include succinct comments) and a README file that explains how your results can be reproduced. For example, the README file can be a commented Matlab script that sets up the data and calls your code.
- Two projects (I will accept suggestions for these):
- Programming an optimization method for some problem
- Reviewing a research paper related to optimization
- Exam: in-class, consisting of problems and conceptual questions
- NEOS Guide: information about most areas of optimization
- Optimization Online: a repository of eprints about optimization
- Matlab Optimization Toolbox. You can see some demos by running Matlab from an OGI PC and typing demo toolbox optimization in the command window. But note that you will be writing your own code, rather than using the Toolbox.
- Tutorials and books
- Matrix identities (handy formulas for matrix derivatives, inverses, etc.):
If you have never used Matlab, there are many online tutorials, for example:
