31个城市的VRP进行蚁群算法求解的matlab源码-31 cities, ant colony algorithm for VRP to the matlab source code

用matlab解决vrp问题,本程序为遗传算法解决基本VRP问题的例程。各供货点距离矩阵及遗传算法参数在VRP.M中给出。以路径长度作为遗传算法的适应度函数，约束函数通过在LEN中增加惩罚因子体现，本程序简便起见将不满足约束的直接加100；-Vrp matlab to solve the problem with the program for the genetic algorithm to solve the basic problem VRP routines. The delivery

VRP指一定数量的客户，各自有不同数量的货物需求，配送中心向客户提供货物，由一个车队负责分送货物，组织适当的行车路线，目标是使得客户的需求得到满足，并能在一定的约束下，达到诸如路程最短、成本最小、耗费时间最少等目的(VRP refers to a certain number of customers, each with different amount of demand for goods distribution center to provide goods to customers

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。(The simulated annealing algorithm derived from the principle of solid annealing, heating the solid to a sufficiently high, let it slowly cooling, he

TS算法通过引入一个灵活的存储结构和相应的禁忌准则来避免迂回搜索，并通过藐视准则来赦免一些被禁忌的优良状态，进而保证多样化的有效探索以最终实现全局优化(TS algorithm by introducing a flexible storage structure and corresponding tabu criteria to avoid circuit search, and the contempt of criterion to pardon a little good state
