-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...

相比branch and bound,其多了一个Cutting Planes的过程,先用Cutting Planes tighten LP relaxations,然后求解LP relaxations再判断是否有分支的必要。 其伪代码如下: // ILP branch and cut solution pseudocode, assuming objective is to be maximizedILP_solution branch_and_cut_ILP(IntegerLinearProgram initial_prob...
FIGURE 4.25.A TSP and its solution tree after applying branch-and-bound. Branching out to all possible choices guarantees that no potential solutions will be left uncovered. But because the target problem is usually NP-complete or even NP-hard, the solution space is often too vast to traverse...
