Improved Genetic Algorithm for Wave Impedance Inversion

Abstract

Abstract: 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 takesquinary 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 nonlinear method of annealing genetic algorithm to be applied in the inversion of seismic wave impedance.

Key words: seism, genetic algorithm, wave impedance, inversion
