分支定界法(Branch and Bound) 该方法构造一个搜索树,每个节点表示当前城市的部分路径,通过上下界进行剪枝,减少搜索空间。 线性规划与割平面法(Linear Programming and Cutting Planes) 通过线性规划的松弛问题求解TSP,并使用割平面法来逐步排除不满足TSP约束的解。 近似算法不能保证最优解,但能够快速
The tree of the branch and bound algorithm is shown and the user can select more or less details. With the file 4 examples are provided, own examples can be entered, too.NOTE: This program is not suitable for matrices larger than 9x9! 인용 양식 Martin (2025). Branch and ...
总的来讲,就是在branch and bound tree迭代的过程中,根据当前结点的松弛后的线性规划模型(relaxed LP)的解,来检查该解是否有存在子环路subtour,如果有,我们就把执行subtour-elimination时候产生的破圈约束加到正在求解的模型中去; 如果没有,我们就直接接着迭代算法。 当然这个check的过程和branch and bound tree的过...
Branch and cut involves running a branch and bound algorithm and using cutting planes to tighten the linear programming relaxations. Note that if cuts are only used to tighten the initial LP relaxation, the algorithm is called cut and branch.[1] 02 总体描述 前面说过,branch and cut其实还是和br...
