The Nelder-Mead method or downhill simplex method or amoeba method is a commonly applied numerical method used to find the minimum or maximum of an objective function in a many-dimensional space. It is applied to nonlinear optimization problems for which derivatives may not be known. However, the Nelder-Mead technique is a heuristic search method that can converge to non-stationary points on problems that can be solved by alternative methods. The Nelder-Mead technique was proposed by John Nelder & Roger Mead (1965). … Nelder-Mead Method google
