Powell method can be used to solve general unconstrained optimization problems. For the optimization of dimension n<20 objective function, this method can obtain satisfactory results. Unlike other direct methods, the Powell method has a complete set of theoretical systems, so its computational efficiency is higher than other direct methods. The method uses one-dimensional search instead of jumping detection steps. At the same time, the search direction of the Powell method is not necessarily for the downward direction.
