RE: Aplicación de las Derivadas de Funciones de Varias Variables en la Optimización (Modelo de Mínimos Cuadrados)

Yes, the optimal point can be achieved, the trick is always how few points are needed. Of course, if you have data with stochastic noise, then exactly how accurately you can determine the optimal point is also in question. This all becomes much trickier when your surface has odd textures, or a long valley structure within it.
