Any algorithm that has an output of n items that must be taken individually has at best O (n) time complexity; greedy algorithms are no exception. A more natural greedy version of e.g. a knapsack problem converts something that is NP-complete into something that is O (n^2) --you try all items, pick the one that leaves the …

WebJun 7, 2014 · But if we add in a 12¢ coin the greedy algorithm fails as (1×12¢ + 3×1¢) uses more coins than (1×10¢ + 1×5¢). Consider some classic greedy algorithms, e.g. Huffman, Dijkstra. In my opinion, these algorithms are successful as they have no degenerate cases which means a combination of locally optimal steps always equals global optimal.
