解决车辆路径问题，提供了很多有用的算法实现，比如3-opt，2-opt和or-opt等算法，以静态库的形式提供给别人调用。-Solving vehicle routing problem, provide a lot of useful algorithms, such as 3-opt ,2-opt and or-opt algorithm, in the form of a static library available to others call.

运用2-opt算法解决TSP（旅行商问题），满足自定义五个点及自设迭代次数，包括可视化结果。(TSP (Traveling Salesman Problem) is solved by using 2-opt algorithm, which satisfies five custom points and self-designed iteration times, including visualization results.)
