Greedy exchange
Web1) When moving from one group of cookies (i.e. those with the same value b [i]), it's only important how many moves your opponent will still spend in previous group (s). You need dp for that. It's l a s t [ k] in tourist's code, I think. 2) Then, think about what happens even if there is only one group of cookies. WebJun 2, 2024 · When amount is 20 and the coins are [15,10,1], the greedy algorithm will select six coins: 15,1,1,1,1,1 when the optimal answer is two coins: 10,10. Another …

Web• Exchange Property: An optimal solution can be transformed into a greedy solution without sacrificing optimality • Structural bounds: There may be some lower (upper) bound that a valid solution cannot exceed. Sometimes we can prove greedy optimality by showing that greedy achieves this bounds. Can use any approach that proves correctness WebGreedy Analysis Strategies.
