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
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 ...
This is the first of two papers presenting and evaluating the power of a new framework for combinatorial optimization in graphical models, based on AND/OR search spaces. We introduce a new generation of depth-first Branch-and-Bound algorithms that explore the AND/OR search tree using static and...
In this paper, we introduce an exact algorithm for solving LIMIDs that is based on branch-and-bound search. Our approach is related to the approach of solving an influence diagram by converting it to an equivalent decision tree, with the difference that the LIMID is converted to a much ...

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branch and bound脱离不了干系。其实是有很大干系的。在应用branch and bound求解整数规划问题的时候,如下图(好好复习一下该过程): ...
For this problem, existing literature emphasises on heuristics or optimal solutions for special cases, whereas this paper proposes a branch-and-bound algorithm. Several lower bounds for optimal and partial schedules are derived. Also, three dominance rules are deduced, and seven constructive heuristics...
