WebJul 9, 2024 · Prove that the algorithm produces a viable list: Because the algorithm describes that we will make the largest choice available and we will always make a choice, we have a viable list. Prove that the algorithm has greedy choice property: In this case we want to prove that the first choice of our algorithm could be part of the optimal solution. WebOct 8, 2014 · The formal proof can be carried out by induction to show that, for every nonnegative integer i, there exists an optimal solution that agrees with the greedy solution on the first i sublists of each. It follows that, when i is sufficiently large, the only solution that agrees with greedy is greedy, so the greedy solution is optimal.
