Greedy strategy algorithm

WebJun 24, 2016 · Greedy algorithms usually involve a sequence of choices. The basic proof strategy is that we're going to try to prove that the algorithm never makes a bad choice. Greedy algorithms can't backtrack -- once they make a choice, they're committed and will never undo that choice -- so it's critical that they never make a bad choice.
