Abstract

Abstract:

A hybrid fast genetic algorithm (H2O) is proposed on the basis of various characteristics of nature evolution. This algorithm is combined with niche technician, a variety of crossover schemes, multi-populations and catastrophism phenomenons. Last sense, it can efficiently eliminate premature convergence of GA on the nonlinear multi-parameter optimization problem. Through testing seism wave impedance inversion, the result is obviously improved compared with the convention genetic algorithm in the convergence ability and computation efficiency.

Key words: algorithm, wave impedance
