The Nelder–Mead method (also downhill simplex method, amoeba method, or polytope method) is a numerical method used to find the minimum or maximum of an objective function in a multidimensional space. It is a direct search method (based on function comparison) and is often applied to nonlinear optimization problems for which derivatives may not be known. However, the Nelder–Mea… WebDepartment of Statistics, University of Hong Kong, Pokfulam Road, Hong Kong SUMMARY ... (McCullagh and Nelder, 1989, Chap. 9).
