Preliminary information on the graduate course "Discrete and Mixed-Integer Optimization".

More information will appear here shortly.

258B is still listed with the old title "Variational Analysis" in the course catalog.

The new 258B has a completely changed syllabus (see below).

There are no graduate-level prerequisites for this course. In particular, it is completely independent of 258A "Numerical Optimization".

This course will be very different from 258A "Numerical Optimization".

Course Time: Tuesdays and Thursdays 1:40-3:00

Room: TBA

Instructor: Matthias Köppe

Office hours: TBA

Syllabus:

Grading is based 100% on homework. Solving homework will require ability to read and write mathematical proofs, and familiarity with a programming language of your choice. Knowledge of linear algebra and the basics of linear optimization are required.

Topics:

Modeling techniques for integer and mixed integer optimization

Modeling languages

Optimization software

Branch-and-cut technology for combinatorial and mixed integer linear optimization

Cutting plane theory

Primal methods

Nonlinear branch and bound and outer approximation

Global optimization: Spatial branch and bound and convexification

Our textbook:

Bertsimas, Weismantel: Optimization over the Integers, 600 pages, Hardcover, ca. $90

Should be available in the bookstore.

Our textbook is a very up-to-date (2005), comprehensive, and accessible textbook that covers all aspects of integer and mixed-integer linear programming. It is used at MIT and other places for teaching Integer Programming at the graduate level.

I will supplement this by additional material on mixed-integer nonlinear optimization following the most recent developments on the research frontier.

Comparable textbooks:

• Laurence A. Wolsey, George L. Nemhauser, Integer and Combinatorial Optimization, 763 pages, Paperback, ca. $110
• A comprehensive, older (1988) text.
• Laurence A. Wolsey, Integer Programming, 264 pages, ca. $90-$130
• A gentle, and short, introduction to Integer Optimization aimed at the advanced undergraduate and master's level.

For a background on linear optimization:

Most textbooks on linear optimization give sufficient background. Here are two examples:

• Introduction to Linear Optimization by Dimitris Bertsimas and John N. Tsitsiklis
• Linear Programming: Foundations and Extensions by Robert Vanderbei

Further resources:

• Bradley, Hax, Magnanti: Applied Mathematical Programming
• A general introduction to mathematical optimization, including integer linear optimization, from an applied point of view. This is a bit dated (1977), but still a good reading on the basic material.
• A re-typeset version of this 1977 MIT classic is available online as a full text

Software

• COIN/OR, version 1.3.1 ("CoinAll" package)
• This is installed on the Math computers in the directory ~mkoeppe/public/dest-1.3.1/bin
• If you want to install this on your own computer, you can download a binary distribution from http://www.coin-or.org/download/binary/CoinAll/
