【摘要】 BP网络能较好地解决贮灰坝监测系统的预报问题,但容易陷入局部极小值;遗传算法能寻求到全局最优解,因此,将二者结合的突出优点在于可以克服前者经常得出局部极小值解的缺点,而取得全局最优解。将BP算法用于加强遗传算法的局部搜索,并且应用到贮灰坝的监测系统上,取得了较好的效果。更多还原

【Abstract】 BP network can solve the prediction problem of monitoring system, but is apt to plunge into local minimum. Genetic algorithm can find optimal solution, so BP algorithm may be combined with genetic algorithm, which can overcome the shortcomings of BP algorithm. The advantages make people attach importance to combination of both algorithms. The author adopts BP algorithm to strengthen local searching of genetic algorithm and applies it to monitoring system of flyash dam which functions well.更多还原
