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.
