Explain knapsack algorithm

WebFeb 21, 2024 · Practice. Video. An algorithm is a well-defined sequential computational technique that accepts a value or a collection of values as input and produces the output (s) needed to solve a problem. Or we can say that an algorithm is said to be accurate if and only if it stops with the proper output for each input instance.

WebTo make the sum of items become kw, the answer is k ∑ i = 1vi. Therefore, it is easy to extend this to O(DC) by performing ( max, +) convolution with B = [0, v1, v1 + v2, …] on each residue class modulo wi. We will perform wi convolutions and each convolution will take O(C wi) time since B is concave and we are doing ( max, +) convolutions. WebDec 8, 2024 · 0–1 Knapsack Problem.
