| 摘 要： | 利用模拟退火反演过程中废弃的随机搜索的模型解信息，建立起目标的函数的二阶趋势面，根据趋势面的分析结果预测和指导模拟退火的搜索方向，使模拟退火法快速地收敛到全局最优解，数值试验证明，这种方法比传统模拟退火法的计算效率高出十倍以上。

| Abstract: | An approach to solving global optimization and inversion problems is developed. It builds 2-order trend surface analysis of abandoned search information in heuristic nonlinear inversion - simulated annealing. The fundamental of this approach is that SA changes process of random search according to prediction of trend surface analysis with some solutions of search in model space so that it ensures inversion to converge to the global optimum fast and exactly. The numerical test of a typical economics inversion problem has proved that this approach can improve the efficiency of simulated annealing remarkably. |
