the Simplex optimization algorithm?  I've tried the one in the link below,
but I can't figure out if a) I'm using it properly, or b) where to get the
solution.  BTW, I tried some test scenarios using MS Excel's "Solver" and
just can't get this algorithm to match Excel's results (which is spot on).

Are you able to use scipy? It has the simplex algorithm (among many others)
in its optimize module:
