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 4 examples are provided, own examples can be entered, too.NOTE: This program is not suitable for matrices larger than...
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...
2.1.1Branch-and-cut Branch and bound is a widely used technique for exactly solvingMIPinstances[12], which can serve as an exact algorithm proven to reach the optimal solution eventually[13]. Moreover, the branch-and-cut algorithm is currently the most popular architecture forMIP solvers, whic...
Parallel algorithmNew strategies are proposed for implementing algorithms based on Branch and Bound scheme. Those include two minimal spanning tree lower bound modifications, a design based on the fact that edges in the optimal tour can never cross in the euclidean TSP and parallelization of Branch ...

Branch and cut involves running a branch and bound algorithm and using cutting planes to tighten the linear programming relaxations. Note that if cuts are only used to tighten the initial LP relaxation, the algorithm is called cut and branch.[1] ...
