Greedy algorithm questions

WebKruskal’s Algorithm is a famous greedy algorithm. It is used for finding the Minimum Spanning Tree (MST) of a given graph. To apply Kruskal’s algorithm, the given graph must be weighted, connected and undirected. Kruskal’s Algorithm Implementation- The implementation of Kruskal’s Algorithm is explained in the following steps- Step-01: WebMy solution is to pick the 2 largest integers from the input on each greedy iteration, and it will provide the maximal sum ($\sum_{j=1}^{n} l_{j1}\cdot l_{j2}$). I'm trying to proof the correctness of the algorithm using exchange argument by induction, but I'm not sure how to formally prove that after swapping an element between my solution and ...

WebMar 15, 2024 · We can keep doing this exchange until O P T is literally the same knapsack as P, recall P is the knapsack that ALG (greedy algorithm) produces. Therefore, we have proved by contradiction there cannot be a strictly more optimal knapsack than the knapsack produced by ALG, so P is optimal and ALG produces the optimal knapsack. .
