回火退火法作为模拟退火法的改进方法，当退火一定程度时讲温度升高即回火，然后在继续退火，反复即可跳出最优陷阱，保证全局最优解的求解效率质量。-Tempering annealing as an improved method of simulated annealing, speaking when the annealing temperature that is tempered to some extent, and then continue annealed repeatedly to jump out of the best trap, ensure the quality of the global optimum solution efficiency solution.
