模拟退火算法，模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。(Simulated annealing algorithm, simulated annealing algorithm derived from the principle of solid annealing, heating the solid to the full high, let it slowly cooling, heating, the solid particles with the internal temperature rise to disorder symptoms, which can be increased, and slowly gradually cooling particles in an orderly manner, at each temperature to reach equilibrium, and finally at room temperature reaches the ground state, which can be reduced to a minimum.)
