I said in class, yet forgot to post on the blog, that homework #5 is due on April 22nd. By the way, I think I will assign one more homework on the 22nd that will be due May 4th. The final will also be assigned on May 4th, and will be due on the day the final is scheduled to be for our class, which is Thursday May 13th.
Also, here is the Macaulay2 file that illustrates the automated geometric proving and colorability of graphs applications from class.
I have also placed the book An Introduction to Grobner Bases by Adams and Loustaunau on reserve in the math library. The material on colorability of graphs, as well as the applications to linear programming are covered in chapter 2 of that book.
