Aha, I think this is the key to my confusion.
thanks again to all for the help. The example problem was of course just
an example, and as several people noted, it wasn't a working one. I
constructed it in the email only and didn't find the obvious bugs...
Thanks also for the pointer to the simplex method code and linear
programming as a special case. i plan to eventually have fairly
nonlinear objective functions. These simplified test cases are just for
testing out my code.
