We use dynamic programming approach to solve this problem, similar to what we did in classical knapsack problem. This would be highly inefficient, given the computation time. nCn = 2^n possible combinations of n items. This way, choosing from all combination would mean a time complexity of orderĪs there are total nC0 + nC1 +.
#KNAPSACK DEFINITION UPDATE#
MaxProfit = max(maxProfit, profit) // Update max profit. Note the total benefit is (41+41+12+12+2) = 108 with total weight being 57 ( W: // When weight of the combination exceeds Capacity, Break. In this case, the optimal filling will be: Item 3 + 3 + 1 + 1 + 2 Suppose we have three items which is defined by a tuple (weight, benefit). In the Unbounded version of the problem, we are allowed to select one item multiple times, unlike the classical one, where one item is allowed to be selected only once. The objective is to fill the knapsack with items such that we have a maximum profit without crossing the weight limit of the knapsack. Given N items each with an associated weight and value (benefit or profit). Read about the general Knapsack problem here This problem can be solved efficiently using Dynamic Programming. In this case, an item can be used infinite times. This restriction is removed in the new version: Unbounded Knapsack Problem. In the original problem, the number of items are limited and once it is used, it cannot be reused. The objective is the increase the benefit while respecting the bag's capacity. Knapsack problem refers to the problem of optimally filling a bag of a given capacity with objects which have individual size and benefit.
