WebThe implementation of the algorithm is clearly in Θ(n^2). There is a Θ(n log n) implementation and the interested reader may continue reading below (Java Example). Now we have a greedy algorithm for the interval scheduling problem, but is it optimal? Proposition: The greedy algorithm earliest finish time is optimal. Proof:(by contradiction) WebGreedy works! Because “greedy stays ahead” Let 𝑔𝑖 be the hotel you stop at on night 𝑖in the greedy algorithm. Let 𝑇𝑖 be the hotel you stop at in the optimal plan (the fewest nights plan). Claim: 𝑔𝑖 is always at least as far along as 𝑇𝑖. Base Case: 𝑖=1, OPT and the algorithm choose between the same set WebGreedy Algorithms Greedy Algorithms: At every iteration, you make a myopic decision. That is, you make the choice that is best at the time, without worrying about the future. And decisions are irrevocable; you do not change your mind once a decision is made.
