摘要
本文介绍了小波变换以及它的多尺度性,结合局部优化来解决函数的全局优化问题,提出了一种新的全局优化方法.首先给出算法,用matlab编程并给出若干个多峰值函数求解全局最优值的算例,得到了与理论值十分接近的优化结果.说明了该算法具有一定的可行性.
The wavelet transform and its multi-scale are introduced.Combining local optimization,a global optimization method is put forward for solving the global optimization problem of function.The algorithm is given at first,and then the numerical computation of function with a number of multi-peak for global optimization is also given by matlab.The optimization result is very close to the theoretical value,and shows the feasible of this algorithm.
