Re: P.S., regarding optimizers

[Daniel L. Weinreb <dlw at MIT-AI>]

I forgot to say: the reason that associating the optimizers with the
definition the way RMS suggested is right is that the optimizer must, by
its nature, go along with the definition.  If the definition is changed,
the optimizer may need to be changed too.  They both understand the
contract of the function, and if it is changed then they may both have
to be changed.  Therefore, they belong together.
