摘要
文中介绍了传统的遗传算法与BP算法,并分析了它们的不足。提出了一种将遗传算法和BP算法相结合的遗传BP算法,在遗传算法的群体设计中采用小生境技术,防止优秀个体早期退化。并将此方法应用于桩基检测中,实验证明了其正确性和有效性。
In this paper,the principle and disadvantages are analyzed.A new algorithm on genetic algorithm,niche technology is applied in pile illustrates that the new algorithm has better characteristics of Genetic Algorithm and combination of genetic algorithm and back order to avoid the early degenerate of good efficiency. BP algorithm are introduced.Their propagation algorithm is proposed.In network.The experiment in defect of pile illustrates that the new algorithm has better efficiency.
