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.

WebJan 5, 2024 · One of the most popular greedy algorithms is Dijkstra's algorithm that finds the path with the minimum cost from one vertex to the others in a graph. This algorithm finds such a path by always going to the nearest vertex. That's why we say it is a greedy algorithm. This is pseudocode for the algorithm. flunch 63
