Joel Friedman's Math 340 Page
This page concerns Math 340, Section 101, for Winter 201415 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 will be held on Wednesday, October 22, covering material
up to and including October 8. Location will be our usual classroom.

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
"TwoPerson ZeroSum 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 skeletaljust a bare outlinesince
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 to be listed here.
Homework #1, due Sept 15: 9.1(1),(3),(5);
9.2(3),(6);9.3
