List the relative advantages and disadvantages (there can be more than one) of the following methods for a two-variable optimization problem such as Rosenbrock's "banana" function (see Fig. P6.19)...

List the relative advantages and disadvantages (there can be more than one) of the following methods for a two-variable optimization problem such as Rosenbrock's "banana" function (see Fig. P6.19)

(a) Sequential simplex

(b) Conjugate gradient

(c) Newton's method

Would your evaluation change if there were 20 independent variables in the optimization problem?
