The SSA approach, an improvement of Simulated Annealing method (SA), hybridizes the downhill simplex method with the SA method such that SSA possesses the advantages of fast convergence and ability for a global minimum.

• 单纯形-模拟退火算法将单纯形法搜寻机理嵌入到模拟退火算法的基本思想,综合了模拟退火算法全局搜索能力强、单纯形算法局部收敛速度快的优点,是对常规模拟退火算法的一个改进。
