Steps of branch and bound method
網頁routing, crew scheduling, and production planning. All of these problems are NP-hard. Branch and Bound (B&B) is by far the most widely used tool for solv-ing large scale NP-hard combinatorial optimization problems.B&B is, however, an algorithm paradigm, which http://www.universalteacherpublications.com/univ/ebooks/or/Ch7/brancint.htm

The branch-and-bound problem solving method is very similar to backtracking in that a state space tree is used to solve a problem. The differences are that B&B (1)does not limit us to any particular way of traversing the tree and (2) is used only for optimization problems.
