Newton type method
WitrynaWe give three types of stationary points and present the relationships among the three types of stationary points and the global/local minimizers. Then we design a gradient projection Newton algorithm, which is proven to enjoy the global and quadratic convergence property. WitrynaMéthode de Newton. Une itération de la méthode de Newton. En analyse numérique, la méthode de Newton ou méthode de Newton-Raphson 1 est, dans son application la plus simple, un algorithme efficace pour trouver numériquement une approximation précise d'un zéro (ou racine) d'une fonction réelle d'une variable réelle.
