WebMar 22, 2024 · Memoization or Top Down Approach for 0-1 Knapsack Memoization is a technique of improving the recursive algorithm. This involves making minor changes to the recursive code such that we can store the results of intermediate subproblems. The main problem with recursion was that a particular subproblem is solved multiple times. WebThe use of 2-D array of size ‘N * W’. 3. Method 3: This method uses Memoization Technique (an extension of recursive approach). This method is basically an extension to the recursive approach so that we can overcome the problem of calculating redundant cases and thus increased complexity.
