摘要
波动方程反演是典型的非线性反问题 .本文提出了用混合最优化法反演层状介质参数 .混合最优化法将广义模拟退火与局部最优化方法结合 ,能较好地利用两者的优点 .在本文中 ,局部最优化算法采用线性化迭代算法 .通过数值结果表明反演方法的正确有效性 .
Inversion of the wave equation is known to be a highly non-linear problem. By combining the generalized fast-simulated annealing method with a local inversion method,a hybrid optimization inversion method was proposed. Numerical examples were presented to prove the feasibility of the method.
