Greedy stays ahead
WebTwo fundamental approaches to proving correctness of greedy algorithms • Greedy stays ahead: Partial greedy solution is, at all times, as good as an "equivalent" portion of … WebThe proof idea, which is a typical one for greedy algorithms, is to show that the greedy stays ahead of the optimal solution at all times. So, step by step, the greedy is doing at least as well as the optimal, so in the end, we can’t lose. Some formalization and notation to express the proof. Suppose a 1;a 2;:::;a
