使用mathematica实现遗传算法,以一个简单的震荡函数求解为例。
简单介绍就是一个使用Mathematica进行二维流场模拟的例子,你还可以自己控制各项参数进行调整。展示文件和原始代码都传上来了。 A 2D fluid velocity field is represented using streamlines. A streamline is tangent to the velocity field everywhere. Streamlines are plotted for the velocity field generated by the components of the velocity vector. You can vary the values of the coefficients, exponents, and constants of each component u and v of the velocity vector. You can restrict the range with the controls at the top.
