方法采用pH梯度萃取法从大黄中提取出蒽醌成分,采用体外实验及二分法测定各成分的抑菌效果。

A new method to construct nested interval-interval evolution algorithm is presented according to the questions that traditional bisection method has low convergence rate and low accuracy and search one root in some interval in constructing nested interval to solve equation.

针对传统的二分法在构造区间套求方程的根时存在收敛速度慢、精度低,而且在一个区间内只能搜到一个根的问题,提出了一种新的区间套构造方法——区间进化算法。

To improve the GP,bisection method is employed to find an optimal step size so as to improve.

文章首先介绍了GP算法的理论基础及算法步骤,然后分析了算法产生收敛问题的关键原因,针对其高精度解不能很好收敛的问题,采用二分法改进了其中关键的步长确定策略,提出了改进的GP算法(IGP,Improved GP),并通过计算实例比较了GP和IGP的表现,分析了IGP的优势。
