Greedy algorithm: highest value first vs earliest deadline first

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 algorithms have some advantages and disadvantages: It is quite easy to come up with a greedy algorithm (or even multiple greedy algorithms) for a problem. Analyzing the run time for greedy algorithms will generally be much easier than for other techniques (like Divide and conquer).
