WebBranch 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. It is an algorithmdesign paradigmfor discreteand combinatorial optimizationproblems, as well as mathematical optimization. WebJul 29, 2024 · Branch & bound technique gets its speed benefit from branching on only one single node each time which is most probable to lead to the result (has the highest estimated value). Example : In your first iteration assume that you have found 2 nodes with estimated values node1: 110 node2: 80 You are pushing them both to your queue.
