一个既不是局部极大点又不是局部极小点的平稳点称为一个鞍点。

A stationary point which is neither a local maximum nor a local minimum point is called a saddle point.

后者需要初值足够接近结果，以避免陷入讨厌的局部极小点并节约宝贵的计算时间。

And for the latter, initial value should be sufficiently close to the result to avoid the nasty local minimum and save the precious computation time.

用这种方法可以有效逼近解的局部极小点，但不一定能得到最佳解或最佳的分辨率。

This method can approach local extreme value available, but it is not the optimal solution or optimal resolution.
