摘要
为解决地震波阻抗反演的实际问题,在自然界生物遗传过程优选和进化原理的基础上对传统的遗传算法进行了改进,提出了改进的遗传算法(GA)首先取消传统的二进制编码、解码过程,而使用五进制进行编码;然后是在遗传操作中引入Boltzmann生存机制。使用改进的遗传算法对地震波阻抗进行反演,目标函数可以达到数量级,这就使退火遗传算法的非线性方法能够应用于地震波阻抗反演中。
Improved genetic algorithm takes improving on traditional genetic algorithm for practical question of seismic wave impedance inversion,based on the best choice and evolutional principle in natural biology genetic process.This algorithm takes quinary system coding instead of binary system coding before introducing Boltzmann exist mechanism in genetic operation,and can be used for inversion of seismic wave impedance so that allows object function to meet an order as required and allows non linear method of annealing genetic algorithm to be applied in the inversion of seismic wave impedance.
