Greedy algorithm for 0-1 knapsack problem
WebViewed 6k times. 1. We have a 0-1 knapsack in which the increasing order of items by weight is the same as the decreasing order of items by value. Design a greedy algorithm and prove that the greedy choice guarantees an optimal solution. Given the two orders I imagined that we could just choose the first k elements from either sequence and use ... Web0/1 Knapsack problem: the brute-force approach 0/1 Knapsack problem: the brute-force approach Let’s first solve this problem with a straightforward algorithm: • Since there are n items, there are 2n possible combinations of items. • We go through all combinations and find the one with the maximum value and with total weight less or ...
