基本思想 分支限界法常以广度优先或以最小耗费(最大效益)优先的方式搜索问题的解空间树。 在分支限界法中,每一个活结点只有一次机会成为扩展结点。活结点一旦成为扩展结点,就一次性产生其所有儿子结点。在这些儿子结点中,导致不可行解或导致非最优解的儿子结点被舍弃,其余儿子结点被加入活结点表中。 此后,从活结点...
Branch-and-bound methods belong to the category of exact methods: they provide one or all of the optimal solutions of the considered instance for various optimization problems. Practical use of a branch-and-bound method requires the specification of several ingredients; a general description is ...

A branch-and-bound type re- finement procedure is implemented to reduce the conservatism. We demonstrate the method on a two-state example from the literature and five-state controlled short period aircraft dynamics with and without time delay in the input to the plant. I. INTRODUCTION We...
Travelling salesman problem using branch and bound (penalty) method calculator 1. A travelling salesman has to visit five cities. He wishes to start from a particular city, visit each city only once and then return to his starting point. The travelling cost of each city from a particular ci...
