WebBranch-and-Bound. The branch and bound algorithm is similar to backtracking but is used for optimization problems. It performs a graph transversal on the space-state tree, but general searches BFS instead of DFS. During the search bounds for the objective function on the partial solution are determined.

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 WebBoth BFS and DFS generalize to branch-and-bound strategies – BFS is an FIFO search in terms of live nodes List of live nodes is a queue – DFS is an LIFO search in terms of live nodes List of live nodes is a stack Just like backtracking, we will use bounding functions to avoid generating subtrees that do not contain an answer node Example: 4 ...
