旅行商问题的算法，采用分枝限界。网上都只有算法描述，没有实现，这里给出了完整实现，并封装成1个类。-TSP algorithm used Branch and Bound. Only online algorithm descr iption, failed to materialize here is the realization of complete, and packaged as a category.

分支限界tsp算法中求下界函数的值。有中文注释。-Tsp branch and bound algorithm for the lower bound of the value function. Chinese Notes.

实验四：分枝限界算法设计 实现课本上旅行售货员问题的分枝限界算法(P225)，随机生成两个规模为10和20的TSP实例，比较算法运行时间。 提交源代码以及实验报告。 -Experiment 4: Design and Implementation of Branch and Bound algorithm for the traveling salesman problem textbooks Branch and Bound algorithm (P225), randomly g
