分析了模拟退火非线性反演方法随机寻优的特点,提出了一种改进的具有较高计算效率的模拟退火方法,该方法采用数论中的均匀试验设计方法来建立候选解在解空间的均匀分布,少量的目标函数计算就能了解目标函数解空间性质,减少了目标函数的计算次数.理论和实际计算表明该方法具有较高的计算效率.

An improved simulated annealing algorithm is presented. In the agorithm, the selected solutions are generated by means of uniform design method, which can make the selected solutions uniformly distribute in solution space. By using this algorithm, the property of object function can be known only by less computation. The times of computing object function can be cut down. The theoretical and actually computed results show that this algorithm can improve the efficiency of computing.
