【摘要】 基于地震子波提取问题的多维性,提出一种将改进粒子群算法与改进遗传算法相结合的优化算法。结合二者的优点,该算法初期采用改进粒子群优化算法,然后将所得个体最好值作为改进遗传算法初始种群继续进行优化,得到最优结果。最后,将该方法应用于地震子估计问题,试验结果证明了该方法的有效性和实用性。更多还原

【Abstract】 A new method combining improved particle swarm optimization(PSO)with improved genetic algorithm(GA)is proposed to the multi-dimension of seismic wavelet estimation.According to the good velocity of PSO and the accuracy of GA,this new algo-rithm first adopts the improved PSO,then get the advanced results via GA.The effectiveness and superiority of the introduced method are demonstrated by experimental results of wavelet estimation.更多还原
