分支定界法(branch and bound)是一种求解整数规划问题的最常用算法。这种方法不但可以求解纯整数规划,还可以求解混合整数规划问题。分支定界法是一种搜索与迭代的方法,选择不同的分支变量和子问题进行分支。 通常,把全部可行解空间反复地分割为越来越小的子集,称为分枝;并且对每个子集内的解集计算一个目标下界(对于...
Branch and Bound(分支定界)是一种解决组合优化和混合整数规划问题的经典算法,通过系统化搜索解空间并结合剪枝策略提高效率。其

3.3.1. If bound(N_i) > B, do nothing; since the lower bound on this node is greater than the upper bound of the problem, it will never lead to the optimal solution, and can be discarded. 3.3.2. Else, store Ni on the queue. ...
A significant number of optimization problems like production planning, crew scheduling can’t be solved in polynomial time, and they belong to the NP-Hard class. These problems are the example of NP-Hard combinatorial optimization problem. Branch and bound (B&B) is an algorithm paradigm widely ...
