浅层地下震动定位方法研究

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。

A Research on Localization Method of Shallow Ground Vibration

The paper presents an idea that using a modified genetic algorithm solves the problem of shallow ground vibration localization, and the model of TDOA is used to calculate the source coordinates .Because of the complexity of the model , the genetic algorithm 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 .
