My brain is going dead. I've been studying for my graduate class most of the evening and actually doing the example problem in the book, because if you don't, you won't be able to work on the actual homework assignment.

There are like 20 different steps to perform on each iteration of the example, which can be like 8-20 iterations. Fortunately the homework assignment only calls for 4 iterations.

The steps for each iteration take an incredible amount of carefullness, logic (this ain't no plug n chug situation), minimization, maximization, substitution of variables, reduction of 4 variable equations, computation of these 4 variable and quadratic equations, substitution of 2 variables into another, tables of values, and lots of looking at like 5 different quations using 4 different variables to compute!

I do not like Lagrange Relaxation or any long and arduous mathematical method that I have to do by hand. I know computer programs probably do this and more!!

I got homework due thursday. I'm kind of iffy about getting it done. I should not have entertained on Monday. Oh well.
