Re: How big a problem can ConstrainedMax handle?

My experience is that the ConstrainedMax is very handy and stylish, not
having to type in the constraints in a conventional tableau form. The
problem is basically number crunching in my opinion, so I used SIMPLX
(simplex) algorithm from Numerical Recipes, being very satisfied with its
limitness and high speed.
