Assignment 6
The last homework of the course is focussed on sensitivity analysis, duality, and the RSM. All the ideas involved have already been covered in class, so it's safe to start work immediately.
About the Deadline: It would be ideal to hand in the work during the last class of the term, on Thursday 20 June, but everybody who needs an extension may submit without penalty any time before 14:00 on Friday 21 June.

Assignment 4
Here are eight questions about duality. The first one is meant to build your intuition. Attack it graphically, without involving the Simplex Method or anything else we have developed in class. The goal is to produce some pictures that illustrate what our general approaches are revealing.

RR   Past Final Exams
The overall curriculum and level of expectations for our course are supposed to match well with the historical characteristics of MATH 340. Here are some recent final exams given by other instructors. Thanks to Professors Anstee and Rechnitzer for sharing. Prepared solutions for these tests are not available. Your instructor is happy to work on these questions together if you get stuck.

RR Web-Powered Simplex Pivoter:
Most web browsers use Javascript, which is powerful enough to execute the Simplex Method on classroom-sized examples. Stefan Waner of Hofstra University supplies a lovely simplex-method script. [Since Javascript works by sending source code to your browser, you can use the "View Document Source" command to see exactly how the method works. If you save a copy on your own machine, it will work even when you are not connected to the internet!]

RR Past Final Examinations:
I will gladly discuss any questions you can find on the Math Department's Past Exam Page, especially ones from MATH 340!
