说明：  模拟退火算法来源于固体退火原理，是一种基于概率的算法，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 arithmetic originates from the principle of solid annealing. It is a probability-based arithmetic. The solid is heated to a full height and then cooled slowly. When heated, the particles inside the solid become disordered with the temperature rising, and the internal energy increases. When slowly cooled, the particles tend to be ordered, reaching equilibrium at each temperature, and finally reaching the ground state at room temperature, the internal energy decreases to the minimum.)
