My graduate Linear Programming class uses Bertsimas & Tsitsiklis's Introduction to Linear Optimization. Are there any alternative texts that I could use to supplement this textbook (mainly the content of Chapter 2 of Bertsimas & Tsitsiklis: extreme point, vertex, basic feasible solution, contains/does not a line, Fourier-Motzkin) at the same level rigor and which contain exercises that I could practice on?
Ideally, I would also like a book with a decent (the more the better) number of pictures that gives geometric intuition behind proofs.
