| Abstract: | In this paper ,a new approach, which is based on simulated annealing algorithm for solving a class of diffusion equation of parameter operator identification of inverse problem, is presented. It transforms the parameter operator identification of inverse problem. It gives a solving example which compares the algorithm of this paper with the genetic algorithm in others literature under Matlab language. The results of numerical simulation indicate this algorithm similarly has practicability and availability. Simultaneously, it has high precision. |
