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:

scipy would be another possibility of last resort. I will take a
look. Thanks.
