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 derived from solid annealing principle, the solid is heated to a sufficiently high, let it cool slowly, when heated, solid particles with temperature becomes disordered state, the internal energy increases, while slowly cooling the particles gradually increasingly ordered at each temperature to reach equilibrium, and finally reach the ground state at normal temperature, which can be reduced to a minimum.)
