BP神经网络，自适应竞争神经网络对地震进行预测实例(BP neural network, adaptive competitive neural networks to predict the earthquake example)

说明：  用遗传算法和模拟退火算法解决旅行商方面的问题(The genetic algorithm and simulated annealing algorithm to solve traveling salesman problems)

This demonstration is intended for people who know something about the theory of the discrete Fourier transform, and who would find it helpful to see some its properties demonstrated graphically, using a programming language. The demonstration shows the form of the Fourier components of a signal in 1-D and in 2-D, and shows how elementary filtering can be applied in the Fourier domain.
