WebBranch-and-Bound. Branch-and-Bound (B&B) is a concept to solve discrete constrained optimization problems (COPs). They are similar to CSPs, but besides having the constraints they have an optimization criterion. In contrast to backtracking, B&B uses Breadth-First Search. One part of the name, the bound, refers to the way B&B prunes the space of ... WebAccording to the bounding values, we either stop there or extend. Applications of backtracking are n-Queens problem, Sum of subset. Applications of branch and bound are knapsack problem, travelling salesman problem, etc. Backtracking is more efficient than the Branch and bound. Branch n bound is less efficient.
