模拟退火算法是一种通用的随机搜索算法，是对局部搜索算法的扩展。与一般局部搜索算法不同，SA以一定的概率选择领域中目标值相对较小的状态，是一种理论上的全局最优算法。-Simulated annealing algorithm is a common random search algorithm is an extension of local search algorithm. Different general local search algorithm, SA with a certain probability target areas selected in a relatively small state, is a theoretical global optimal algorithm.
