This is strictly my personal opinion.

Which optimization solver to pick really depends on the characteristics 
of the data being optimized, how (well) the algorithm is implemented in 
the versions included in Calc, the accuracy goal etc. etc.  It's more an 
art than science, and each user really needs to experiment with various 
solvers to see which one works best for his or her optimization cases.  
My personal opinion is that it is probably beyond the scope of Calc user 
guide to provide any sort of guidance on how to select a solver.

Feel free to disagree with me on this.  I'm not an expert. :-)
