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。(The simulated annealing algorithm derived from the principle of solid annealing, heating the solid to a sufficiently high, let it slowly cooling, heating, temperature rise inside the solid particles with the shape into disorder, can be increased, and slowly cooling particles gradually and orderly, has reached equilibrium at each temperature, finally reached the ground state at room temperature can be reduced. Is the minimum.)
