But if they are asking for REPRODUCIBILITY, that is a very

a gradient-based optimization, which requires numerical derivatives,
for example.

Several of the theoretical stage columns use numerical derivatives.  One
method that my fellow engineer created while he was teaching at Rice.

What I meant was the the results were reproduceble (and smooth)
enough so they could be used in an external gradient-based method
of optimization.

And a couple of methods based on the Boston Inside-Out method.

That must be a reference to Henry Morgan's "Boston Inside Out! Sins
of a Great City!", right? :-)  (Actually, I know what it is).
