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。

-BranchBound_TSP：BB算法主程序。 该branchandbound的搜索树是以优先队列的搜索方式遍历的，结合上期所讲的内容，也可谓是把三种搜索方式的例子都给大家讲了一遍了。 branchandbound过程 02 在此之前，先给大家讲讲最重要的一个点，搜索树的节点定义，节点定义了原问题的solution和子问题...

branch-and-boundheuristicsSummary: We address a special TSP in which the set of cities is partitioned into two subsets: mandatory cities and selective cities. All mandatory cities should be visited once within one of the corresponding predefined multiple time windows. A subset of the selective ...
