计算表达式的实现已经有很多了，但是支持含有中文变量名的表达式计算的功能代码我没有找到，因此我抽取一个计算器程序计算表达式的源码，作了一些修改，使之支持含有中文变量名的表达式。-calculation formula has been the realization of a lot, But Chinese support for the variable name contains the expression of functional calculation code, I did not find, So I take a calculated expression calculator source code, made some changes, so that it supports variable names containing the Chinese expression.

planck.zip: Planck radiation formula size 110 KB. This program calculates the radiated power, integrated between given upper and lower wavelength limits, by a Planck black body at given temperature. Units are degrees Kelvin, watts, and meters. Current values of Planck and other thermodynamic constants are used. Latest update: 8 May 2000. 普朗克辐射计算公式。-planck.zip: Planck radiation formula size 110 KB.

差分进化 （DE） 是一个启发式算法优化的工具。从本质上说，它是提供优质的保障，基于实数编码的遗传算法 [1] 的思想贪婪。随着遗传算法，微分进化算法包含 a 基因突变与交叉操作，但在比较，选择遗传算法的操作的同时，微分进化算法使用一对一的淘汰机制更新人口。适当的微分进化算法在连续域优化问题的优势得到了广泛的应用，进化算法研究热潮。
