In this section we analyze the time and space complexity of the dynamic programming algorithm resulting from (5). In many practical applications the space requirements are the main obstacle for using a dynamic
in O(N*W) Time and Space complexity using both top-down and bottom-up approach, and I can further reduce the space to O(2*W) and time O(N*W) using bottom-up approach [link to the bottom-up approach : Link], but I'm unable to think of a similar space-reduced top-down approac...
Birthday attackWe present a (probabilistic) birthday type attack to Naccache-Stern knapsack cryptosystem. We provide the space and time complexity of this attack alongside with the success probability. Furthermore, we applied successfully the attack for messages of low or large Hamming weight....

Time Complexity: O(N*W)Reason: There are N*W states therefore at max ‘N*W’ new problems will be solved.Space Complexity: O(N*W) + O(N)Reason: We are using a recursion stack space(O(N)) and a 2D array ( O(N*W)). //TABULATION...
time - O(n) space B) Bitmasking Approach: We will update bitmask when we see a better solution O(2^n) time - O(n) space C) Meet-in-the-middle Approach: We will update bitmask when we see a better solution AND ON DP-CALCULATION. Bitmasking - O(2^(n/2) * (n/2)) time ...
that is unknown to the algorithm. an algorithm sees the item growing and can decide to pack it at any point in time. if the algorithm waits too long, however, it will be too late: as soon as its size reaches s , the item disappears and the knapsack remains empty. as we ...
Complete the function knapSack() which takes maximum capacity W, weight array wt[], value array val[] and number of items n as a parameter and returns the maximum possible value you can get. Expected Time Complexity: O(N*W).Expected Auxiliary Space: O(N*W) Constraints:1≤ N ≤ 10001...
Although convergence time is highly important, fast convergence may not always be beneficial, depending on the shape of the fitness landscape or the solution space. If the fitness landscape has many local maxima and the GA is searching for the global maximum, fast convergence is more likely to ...
Knapsack 1andKnapsack 2 I could solve the first one. But wasn't quite able to understand the 2nd one.got me somewhere. could you please solve these few doubts of mine? Was a different approach used just because of the space complexity of the DP matrix?
