2-opt算法求解TSP 2-opt算法求解TSP 2-opt其实是2-optimization的缩写，简⾔之就是两元素优化。也可以称作2-exchange 。2-opt属于局部搜索算法，局部搜索算法（local search algorithm）是解决组合优化问题的有效⼯具。1986年，Glover对局部搜索算法进⾏推⼴衍⽣，提出了禁忌搜索算法（tabu search algorithm）...
2-opt其实是2-optimization的缩写，简言之就是两元素优化。也可以称作2-exchange 。2-opt algorithm最早是由 croes1发表在Operations Research上的一篇名为A Method for Solving Traveling-Salesman Problems的论文（该论文可在OR数据库付费下载）中提出的。最初是用于解决TSP问题的算法。

Differential evolution (DE) is a simple and effective global optimization algorithm. It has been successfully applied to solve a wide range of real-world optimization problems. However, DE has shown some weaknesses, especially the long computational times because of its stochastic nature. This draw...

Indeed, the genetic algorithm is a stochastic optimization algorithm; it is to find an approximate solution of a hard problem. However, genetic algorithm has a great tendency to converge to a local minimum and stay stuck in adverse solutions. To solve this problem, we study in this paper the...
