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 heated to a sufficiently high, let it slowly cooled, heated, the solid particles with the temperature rise becomes disordered state, internal energy increases, and slowly cooling particles gradually increasingly ordered, at each temperature has reached equilibrium, the final temperature reached in the ground state, which can be reduced to the minimum
