WebInterval Scheduling: Proving the simple wrong Greedy algorithms are easy to design, but hard to prove correct Usually, a counterexample is the best way to do this Interval scheduling provided an example where it was easy to come up with a simple greedy algorithm. { However, we were able to show the algorithm non-optimal by using a … WebInterval Scheduling: Greedy Algorithms Greedy template. Consider jobs in some order. Take each job provided ... by induction on r." Basis: i 1 chosen to have min finish time, so f(i 1) ≤ f(j 1) " Ind: f(i r) ≤ f(j r) ≤ s(j r+1), so j r+1 is among the candidates considered by greedy when it picked i r+1
