说明：  “模拟退火”算法是源于对热力学中退火过程的模拟，在某一给定初温下，通过缓慢下降温度参数，使算法能够在多项式时间内给出一个近似最优解。利用模拟退火算法,基于最优下料编码方式,对矩形件进行下料处理。("Simulated annealing" algorithm is derived from the simulation of the annealing process in thermodynamics. At a given initial temperature, the algorithm can give an approximate optimal solution in polynomial time by slowly decreasing the temperature parameter. Based on optimal blanking coding method, simulated annealing algorithm is used to blanking rectangular parts.)
