WebSo that's a greedy proof by induction that a greedy algorithm can be correct. And we might see some more examples of those in, for other algorithms in the lectures to come. Some of the text books call this method of proof greedy stays ahead, meaning you always proof greedy's doing the right thing iteration by iteration. Web1.Which type of proof technique is most representative of a "greedy stays ahead" argument? Select one: a. Proof by contradiction b. Proof by induction c. Resolution …

The general proof structure is the following: Find a series of measurements M₁, M₂, …, Mₖ you can apply to any solution. Show that the greedy algorithm's measures are at least as good as any solution's measures. (This usually involves induction.) Prove that because the greedy solution's WebI Claim ( greedy stays ahead ): f (ir) jr for all r = 1 ;2;:::. The rth show in A nishes no later than the rth show in O . Greedy Stays Ahead I Claim : f (ir) jr for all r = 1 ;2;::: I Proof by induction on r I Base case (r = 1 ): ir is the rst choice of the greedy algorithm, which has the earliest overall nish time, so f (ir) f (jr) Induction Step theraband rollen
