崔-Lawson和Logistic方程参数的优化估计方法

An optimal method of parametr estimation for Logistic and Cui-Lawson equations.

本文提出用单形寻优与微分方程数值解法的联合方法,进行生态学中一些微分动力系统的参数的优化估计。用这种方法来估计崔-Lawson和Logistic方程的各参数效果极好。

This paper develops a method of parameter estimation for some differential dynamic systems in ecology. This method combines simplex method for optimizing a function with Gill-method of numeric solution of a differential equation, The results of parameter estimation of Logistic and Cui-Lawson equations shows a good adaptation of this method.
