Knapsack branch and bound example
WebAs an example, let's go back to the 0-1 Knapsack Problem. problem, so we can use branch and bound for it. Remember, what we're going to look at right now is not the best-first search, but the breadth-first search. We draw the tree in the same way as for the backtracking algorithm.
