-TSPInstanceReader：TSPLIB标准算例读取用。 -PriorityQueue：优先队列。 -Node：搜索树的节点。 -City：保存城市的坐标，名字等。 -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...
01 什么是branch and bound(定义)? 1.1 官方一点[1] Branch and bound (BB, B&B, or BnB) is an algorithm design paradigm for discrete and combinatorial optimization problems, as well as mathematical optimization. A branch-and-bound algorithm consists of a systematic enumeration of candidate solutions...

This demonstration shows the single steps of nearest neighbour, hungarian method (munkres algorithm) for assignment problem, branch and bound for symmetric or asymmetric cost matrices. The tree of the branch and bound algorithm is shown and the user can select more or less details. With the file...

按照某一个标准在节点表里储存，后续取点删点。2、方法应用 下边以bb在求解tsp中的应用来说明，不同问题思路相近，大同小异。求解步骤如下：（1）规约费用矩阵。即使费用矩阵中每一行每一列都包含0元素，此时规约系数就是该问题的一个下界。3、算法实现 以28个点的tsp为例，测试结果如下：
