WebNov 8, 2024 · The Knapsack Problem is used to explain both the problem and the solution. It derives its name from the limited number of things that may be carried in a fixed-size knapsack. We are given a set of items with varying weights and values; the goal is to store as much value as possible into the knapsack while staying within the weight limit.

A Complete Guide to Solve Knapsack Problem Using Greedy Method

WebJun 7, 2014 · 1 Answer. There are no greedy algorithms for 0-1 Knapsack even though greedy works for Fractional Knapsack. This is because in 0-1 Knapsack you either take ALL of the item or you don't take the item at all, unlike in Fractional Knapsack where you can just take part of an item if your bag overflows. This is crucial. WebWe add values from the top of the array to totalValue until the bag is full i.e. totalValue<=W ( where W is Knapsack weight). Here is the implementation of the above knapsack problem in C++ and Java.

WebSort the array in decreasing order using the value/weight ratio. Start taking the element having the maximum value/weight ratio. If the weight of the current item is less than the current knapsack capacity, add the whole item, or else add the portion of the item to the knapsack. Stop adding the elements when the capacity of the knapsack becomes 0.
