摘要: 遗传算法在地球物理勘探领域中已经得到越来越多的应用。但通常遗传算法中普遍使用的二进制编码其编码的长度比较长,会浪费存储空间和增加译码的工作量。通过一个简单的地球物理反演问题的计算结果可以看出,在某些情况下,一些别的进制的遗传算法能够取得较高的计算精度或较快的计算速度,极大地提高了遗传算法的效率,显示出其相对于传统的二进制编码的优越性。这对在以后的研究工作中用遗传算法进行地球物理反演提供了一个很好的思路。

Abstract: Genetic algorithm (GA) has been widely used in geophysical prospecting. However, the conventional binary coding in GA may occupy huge amount of computer memory and add the load of decoding because of its long code. In a simple geophysical inversion, some other encoding scales show their superiority to binary coding for highly calculating accuracy and faster calculating speed, improving the efficiency of GA. This result provides for a good think ing to further study of application of GA in geophysical inversion.
