This is great. I had a college course that basically taught only the simplex algorithm - we did all all of the iterations by hand using tableaus and matrices.

We are using operations research optimization techniques at my side project, StaffJoy. The greatest innovation in usability of OR has been the JuMP project - there is now a fairly universal way to express optimization problems that is lower-level than Excel and higher-level than C. http://juliaopt.org http://juliaopt.org
