用改进的模拟退火法反演子波参数

Wavelet parameter inversion by the modified simulated annealing method

本文对模拟退火法做了分析，提出了在于波参数反演中对模拟退火法的四种改进措施，即加温过程、记忆功能、回火过程、返回搜索，从而有效地解决了模拟退火法初始温度难以选择问题、从全局最优跳出问题、最终解在最优解附近而非最优解问题。并把该方法用于于波参数反演，取得了成功。

In the paper, we analyze the simulated annealing method and put forward four kinds ofmodification measures for the simulated annealing method in the wavelet parameter inversion, i. e.the temperature increment process, the memory function, the tempering process, and the returnsearch. Thus some problems such as the selection of initial temperature have been solvedeffectively. We app1y the method to the wave1et parameter inversion and achieve a success.
