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.
