local minimum的用法和樣例：
例句
- A stationary point which is neither a local maximum nor a local minimum point is called a saddle point.
一個既不是局部極大點又不是局部極小點的平穩點稱為一個鞍點。 - At the same time it can make the solution escape local extreme value and cause the overall optimization capacity when the solution approximates the minimum point.
當解逼近當前極小點的后，動態方程又能使解逃逸局部極值，使其具有全局尋優能力。
