WebThe downhill simplex method of optimization is a "geometric" method to achieve function minimization. The standard algorithm uses arbitrary values for the deterministic factors that describe the "movement" of the simplex in the merit space. While it is a robust method of optimization, it is relatively slow to converge to local minima. WebThe Downhill Simplex method is configured to make a fixed amount of iterations that limits its running time. In the current case we may also force the stop of the evaluation of the target function if its running time exceeded the current worst time achieved far. The Downhill Simplex methods terminates when the last iteration finishes.
