Greedy fractional knapsack algorithm

WebMay 10, 2015 · For fractional knapsack, this is very easy to show: we take any element of X, say b. If w a >= w' b (where w a is the weight of a, and w' b is the weight b has in the solution X ), we can replace b with as large a fraction of a as possible. Because a is the item with the largest value-density (this is our greedy choice), this will not make the ...

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. http://www.columbia.edu/~cs2035/courses/csor4231.F11/greedy.pdf
