Dynamic programming traceback

WebIn this dynamic programming problem we have n items each with an associated weight and value (benefit or profit). The objective is to fill the knapsack with items such that we have a maximum profit without crossing the weight limit of the knapsack. Since this is a 0 1 knapsack problem hence we can either take an entire item or reject it completely. WebDynamic Programming Traceback Traceback can again be done the same way for DP as was done for memoization. The text uses the method of storing choices, in an array s. This is included in Matrix-Chain-Orderand in Print-Optimal-Parens. Note that dynamic programming requires you to figure out the order in which to compute the table entries, …
