| Abstract: | In this paper we troduce the basic principles of simulated annealing algorithm and implementation steps.Simulated annealing algorithm is introduced in MT data inversion,whose forward problem has the characteristics of nonlinear and multi-parameter.We use the special cooling mode and select the appropriate mechanisms to improve processing speed and computational accuracy.We combined with specific inversion algorithm and implementation method to use different theoretical MT forward models to verify and obtain good results. |
