python - Difference between scipy.optimize.fmin and scipy.optimize.minimize

Question

I'm learning python to make models these days. I read the documentation of scipy.optimize.fmin. It also recommends scipy.optimize.minimize. It seems that scipy.optimize.minimize is a more advanced method. Real wonder what's the difference between these two.

Answer 1

scipy.optimize.minimize是一个高级界面，可让您从广泛的求解器中进行选择，其中之一是 Nelder–Mead。scipy.optimize.fmin是使用 Nelder-Mead 的特殊求解器。有关minimizeNelder–Mead 的特定子文档，请参见此处。
