If you terminate the branch and bound code early you will usually have a measure of the quality of the best known solution as branch and bound algorithms maintain information on global upper and lower bounds.
WebBranch and Bound Definitions: • Branch and Bound is a state space search method in which all the children of a node are generated before expanding any of its children. • Live-node: A node that has not been expanded. • It is similar to backtracking technique but uses BFS -like search. • Dead-node: A node that has been expanded Branch and bound (BB, B&B, or BnB) is a method for solving optimization problems by breaking them down into smaller sub-problems and using a bounding function to eliminate sub-problems that cannot contain the optimal solution.
