11. More robust methods have been explored, such as branch and bound and piecewise linear network. 12. Additional constraints can be added and the process repeated indefinitely using a branch and bound approach. 13. An exact solution can be found using branch and bound techniques which utilize relaxation ( approximation ). 14. For example, the branch and cut method that combines both branch and bound and cutting plane methods. 15. The method in steps 7-13 seems to me to be akin to branch and bound techniques. 16. :I am not fully sure I understand your proposed method, but it sounds like branch and bound . 17. The knapsack problem has well-known methods to solve it, such as branch and bound and dynamic programming. 18. MINTO is a software system that solves mixed integer programming problem by a branch and bound algorithm with linear programming relaxations. 19. As well as cutting plane methods, Dantzig, Fulkerson and Johnson used branch and bound algorithms perhaps for the first time. 20. A best-first branch and bound algorithm can be obtained by using a priority queue that sorts nodes on their-value.
