This subject is introduced in multivariable calculus, and in more detail in some
numerical analysis courses. Graphing is one common technique for identifying
promising search ranges if the number of variables can be reduced to one or two.
Analytical identification of asymptotes, extrema, and zeros can also be employed
to set bounds/starting points for searching, but those topics are in general
completely orthogonal to the topic of this mailing list... which is R.
