1) optimal approximate value
最优近似值
1.
The author analyses the mean square of functional approximate value by using the theorem of error propagation, and comes to the conclusion that the approximate value z=f(x,y) of binary function z=f(x,y) is not the optimal approximate value.
本文运用误差传播定理对函数近似值的均方误差进行了分析,得出二元函数z=f(x,y)的近似值(?)=f(?)并非是最优近似值这一结论。
3) approximate optimal solution
近似最优解
1.
Then with the help of four-step method in the literature,the approximate optimal solution for the system is worked out.
然后借助文献[1]中四步法,求出这种具有时滞的广义时间最优控制的近似最优解。
4) optimal approximate solution
最优近似解

It also gives the necessary and sufficient condition under which its solution exists and proper defined optimal approximate solution.
研究一类系数矩阵相互交错的二元复矩阵方程组,给出其有解的充要条件和适当定义的最优近似解,并给出一个应用背景的实例。
5) optimized Born approximation
最优Born近似
6) near-minimizer
近似最小值
1.
It is then proved that the wavelet approximation is a near-minimizer of the functional which has to be minimized to solve th.
有鉴于此,文中构造了可用于非线性滤波算法的一族分段n次小波阈值参数滤波器函数,证明了求解去噪问题必须使得泛函取最小值,而小波逼近是该泛函的近似最小值,可以用来替代Donoho的软阈值滤波器,而且次数n越大,逼近效果越好;同时证明了该n次滤波器的极限是一理想低通滤波器。
补充资料：全局最优值
分子式：
CAS号：
性质：又称全局最优值。最优化问题中从整体考虑求得的最优结果。全局最优点可能不只一个，但全局最优值只有一个。
