提出一种利用改进遗传算法解决浅层地下震动定位的问题,模拟时差定位模型进行震源坐标的求解,由于模型的复杂性,采用了浮点数编码的遗传算法,引入一种自适应的交叉算子和变异算子。实验结果表明,在保证种群数量的情况下,该算法性能大大优于一般遗传算法,能快速找到逼近全局最优的解,并且精度更高。

The paper presents an idea that using a modified genetic algorithm solves the problem of shallow ground vibration locali -zation, and the model of TDOA is used to calculate the source coordinates .Because of the complexity of the model , the genetic algo-rithm of float coding is adopted to introduce an adaptive crossover operator and an adaptive mutation operator .The experimental results show that when the populations are guaranteed , the algorithm performance is greatly superior to general genetic algorithm , and can quickly find the approximate global optimal solution , the precision is higher .
