| Abstract: | Owing to computers providing great advantage in iterative calculation,the non-derivative algorithms have great potential applications to scientific research.Nelder-Mead Simplex(NMS) algorithm is a technique for minimizing an objective function in a multiple-dimensional space without differentiation,proposed by Nelder and Mead(1965).As a simple non-derivative technique,NMS algorithm is widely introduced in many computational books and used in numerical computations,and Matlab implements this algorithm for in... |
