Branch & bound algorithm
WebI am working toward applying the Knapsack algorithm to data sets containing 10,000+ items. I successfully implemented the DP Knapsack on smaller sets, but at a certain point memory becomes an issue, which is why I switched over to the branch and bound method. – wikenator. Mar 11, 2014 at 1:02. So I replaced bound += (k - wt) * (v [j] / w [j ... WebIn order to solve the problem using branch n bound, we use a level order. First, we will observe in which order, the nodes are generated. While creating the node, we will calculate the cost of the node simultaneously. If we find the cost of any node greater than the upper bound, we will remove that node.
