n.極小化；求最小參數(shù)值

This algorithm realizes the efficient clustering by minimizing the corresponding cost function iteratively. 該算法通過迭代優(yōu)化，使得相應的代價函數(shù)最小化，最終得到有效的聚類結(jié)果。

The inverse solution was obtained through minimizing the object function using CGM based on the direct problem. 反問題的解在正問題的基礎上通過共軛梯度法最小化目標函數(shù)得到。
