WebbSimulated annealing is an algorithm based on the physical annealing process used in metallurgy. During physical annealing, the metal is heated up until it reaches its annealing temperature and then is gradually cooled down to change it into the desired shape. Webb其实模拟退火（SImulated Annealing）算法的思想就是来源于物理的退火原理，也就是降温原理。先在一个高温状态下（相当于算法随机搜索），然后逐渐退火，在每个温度下（相当于算法的每一次状态转移）徐徐冷却（相当于算法局部搜索），最终达到物理基态（相当于算法找到最优解）。
