Web4.1 Interval Scheduling: The Greedy Algorithm Stays Ahead 117. The most obvious rule might be to always select the available request that starts earliest that is, the one with minimal start time s(i). This way our resource starts being used as quickly as possible. Web“Greedy Stays Ahead” Arguments. One of the simplest methods for showing that a greedy algorithm is correct is to use a “greedy stays ahead” argument. This style of proof works by showing that, according to some measure, the greedy algorithm always is at least as far ahead as the optimal solution during each iteration of the algorithm.

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 WebIn using the \greedy stays ahead" proof technique to show that this is optimal, we would compare the greedy solution d g 1;::d g k to another solution, d j 1;:::;d j 0.
