这是在GPU上进行高速数字计算的数学库函数，以实现通用GPU计算-This is the GPU on the high-speed digital computing mathematical library functions in order to achieve universal GPU computing

Gryphon is a Java-based computational fluid dynamics code written to solve the quasi 1-D Euler equations.

整个算法分成三部分，第一个部分是神经网络整体结构的确定，然后是遗传算法对参数的优化，然后便是利用已经优化好的参数，利用神经网络进行预测。我们根据需要优化的权值以及阈值的数量确定算法个体的长度。个体通过适应度函数计算他们的适应度，根据适应度的大小，我们使用轮盘算法，确定他们的遗传，交叉还有变异等过程，优化以后的BP神经网络可以更好地收敛。
