【Abstract】 To counter the drawbacks (local ultra little and slow convergence speed) of BP network, this paper designs genetic neural networks with the aid of genetic algorithms and efficient measures to improve algorithm functions. By applying the algorithms to some examples and practical lithologic recognition, the results show that the algorithms are effective.更多还原
