Greedy Algorithms: Knapsack Problem - School of Science …
WebThe Greedy Algorithm is a popular optimization method for solving the fractional knapsack problem. 8. Transportation Problem - The transportation problem is the process of optimizing the cost of shipping goods from multiple sources to multiple destinations subject to capacity constraints. WebGreedy We can solve the fractional knapsack problem with a greedy algorithm: 1. Compute the value per pound (vi/wi) for each item 2. Sort the items by value per pound 3. The thief then follows the greedy strategy of always taking as much as possible of the item remaining which has highest value per pound. 20 how does aldosterone reach the kidney
