Simulated Annealing Algorithm in C++ - C++ Programming

Webb其实模拟退火（SImulated Annealing）算法的思想就是来源于物理的退火原理，也就是降温原理。先在一个高温状态下（相当于算法随机搜索），然后逐渐退火，在每个温度下（相当于算法的每一次状态转移）徐徐冷却（相当于算法局部搜索），最终达到物理基态（相当于算法找到最优解）。 Webb模拟退火算法（simulated annealing，SA）来源于固体退火原理，是一种基于概率的算法。. 算法思想为：先从一个较高的初始温度出发，逐渐降低温度，直到温度降低到满足热平衡条件为止。. 在每个温度下，进行n轮搜索，每轮搜索时对旧解添加随机扰动生成新解 ...
