Joel Friedman's Math 340 Page

This page concerns Math 340, Section 101, for Winter 2014-15 Term 1 (i.e., Fall 2014). The dates of exams, once announced, will not change; all other dates, homeworks, etc. are subject to change.

Not all course materials are available at all times (especially solution sets to homeworks).

Materials here are not necessarily free of errors; some corrections might only be announced in class.

Midterm The midterm was held on Wednesday, October 22, covering material up to and including October 8: the handout on game theory, Chapters 2 and 3, and the applications of Chapters 2 and 3 to game theory (see the blog and the homework exercises). Here is the midterm with solutions; the midterm was scaled by s(x), where x is your raw score out of 30, given by: 5x if x <= 10, 3x+20 if 10 <= x <= 25, and 4x-20 if x >= 25 (so 10 scales to 50, 15 to 60, 25 to 80, etc.) Here is a draft of the note sheet that will be provided to you. You should be able to do all the homework problems, exercises from the handout, and all Sample Exam Problems (see below) from Topics 1 and 2. Location will be our usual classroom; the exam will be 40 minutes long (it will begin some 10 or so minutes after 2pm); you will be seated in alphabetical order by last name (as it appears on my class list).
Basic Materials Here is a general overview of this course. We will first follow Matrix Games and Poker (a supplemental article), which may be updated periodically; we will also refer to "Two-Person Zero-Sum Games," by Alan Washburn. We then follow the textbook, "Linear Programming" by Vanderbei, 4th edition; it is available to anyone with a CWL account. We will then revisit matrix games and poker. Other applications will be covered as time permits.
Blog Here is a general skeletal blog for this course. This will show where we are in the text, and list some of the key points, terminology, etc. It is skeletal--just a bare outline--since we will follow the supplemental article and textbook very closely. Here are two slides from September 19: maple_first_lp.txt, and maple_first_game.txt, illustrating two applications of the simplex method. A slide about a large feasibility question, discussed on September 26, is your_task190.txt.
Homework Homework to be listed here.
Homework #1, due Sept 15: 9.1(1),(3),(5); 9.2(3),(6);9.3 from "Matrix Games and Poker." Homework was graded out of 9; solutions.
Homework #2, due Sept 22: 9.4, 9.7, 9.8, 9.12. One additional statement was added to 9.8, to make things easier, as of September 15; make sure you hit the "refresh" button to get the latest version. Homework was graded out of 12; solutions.
Homework #3, due Sept 29, is given here. Homework was graded out of 9; solutions.
Homework #4, due Oct 6, is given here. It was graded out of 10; 3 points for the first two problems, and 4 points for the last problem. Solutions.
Homework #5, due Oct 17, is given here. Solutions.

No further homework until one week after the midterm.
Office Hours Joel Friedman (Instructor): by appointment, unless posted otherwise.
