这是解决优化问题的遗传算法压缩包，实用性强，可以应用于不同的专业领域。(This is a genetic algorithm to solve optimization problems compressed, practical, can be applied to different areas of expertise.)

对心电信号进行滤波处理后，计算RR间隔，进而求得瞬时心率和心率变异系数，通过对RR间隔的变化曲线进行频谱分析，从而求得各个自律神经活动的评价指标(After filter processing is performed on the ECG, the RR interval is calculated, and then seek the instantaneous heart rate and heart rate variability coefficient, spectral analysis through the curves of changes in the RR interval, to thereby obtain the evaluation index for each of the autonomic nervous activity)

感应电动机的参数辨识，用于负荷建模的参数辨识的适应度函数，可以用遗传算法进行求解。(Induction motor parameter identification, the fitness function for load modeling parameter identification, we can use genetic algorithms to solve)

Determine the SNR for a quadrature delta-sigma modulator using simulations. The modulator is described by a noise transfer function (ntf) and the number of quantizer levels (nlev). The ntf/stf may be given in ABCD form. The band of interest is defined by the oversampling ratio (R) and the center frequency (f0).
