| 摘 要： | 针对ＢＰ网络在连接权的赋值和调整方面存在着固有不足的缺陷，尝试应用近些年发展起来的浮点遗传算法对ＢＰ网络的连接权进行优化，应用改进的ＢＰ网络对四平市地下水水质进行评价，结果证明，浮点遗传算法对ＢＰ网络连接权的优化有很好的效果。

| Abstract: | BP-network is widely applied in many fields. But BP-network has some inherent deficiencies in assignment and adjustment of weights. In actual application, BP-network is difficult to converge so as not to achieve the prospective purpose. In allusion to these deficiencies in BP-network, this article makes an attempt to apply Float-encoding Genetic Algorithms(FGAs) developed in recent years to optimize the weights of BP-network. And it gets over these deficiencies in BP-network. The paper uses the improved BP-network to evaluate groundwater quality in Siping city.The result proves that FGAs achieve better effect. |
