Final Exam scheduled for Tuesday, April 19, 2016 from 7:00-10:00pm in Buchanan A 101. We will be writing the 3 hour exam with the other section.

Our midterm is scheduled for Wednesday Feb 24. Arrive early!

This course would be more properly called Linear Optimization, optimizing a linear objective function subject to linear constraints. The word `programming' is not used in the sense of computer programming. My best reading of Dantzig's description of the term is that the word programming refers to the program of activities given by a solution. There will be no computer programming in this course although for certain assignments you will be asked to use LINDO, a fairly user friendly software package for Linear Programming.

For Section 202, 12-1 MWF January 2016 in BUCH A103. (There is a second section called 201 scheduled for 9:30-11 TTh in MATH 104 taught by Omar Antolin Camarena that will be run partly coordinated with this section.)

My office is Mathematics Annex 1114. I will be in most days by 9:00. I will schedule office hours in the new year. Most assignments/quizzes/midterm will be set for Fridays. You could review some linear algebra concepts particularly the basics of matrix multiplication and change of basis.

The basic course material will be covered in about 9 weeks allowing 3 weeks to do applications and a topic of students choice (Game Theory? Karush-Kuhn-Tucker conditions useful in Economics and Non-Linear Optimization? More Applications?)

George Dantzig, who invented the Simplex method died May 13, 2005 at age 90. An obituary is at Obituary

I will be putting some course materials on the web in pdf format. I would not recommend printing them up too far in advance of lectures since they may change. They look authoritative when typed so be wary. They may look perfect but still contain errors! The text by Vasek Chvatal is an excellent reference but it can be short on examples and the problems in the text are not very good for our course. In addition we cover several topics that are not covered in much depth in the text. Hence we have our own supplementary notes. You will enjoy the later chapters on applications in the text e.g. Chapter 11 and on.

There is a computer lab in LSK 310 (and maybe LSK 121) (LSK is the Klinck Building) whose doors are open at various hours during the day. You either should choose a time with no labs or, because we are fairly far through the term, you could work quietly at the back of the lab even if a lab is scheduled (assuming there are some empty computers). Your ID is the first 8 characters in lower case of your name as recorded first name,middle name(If you have one), final name. The password is set to capital S followed by the first 7 numbers of your student ID. You can change your password. You want to access the windows system and click on LINDO.
