C program knapsack problem using the 3-step greedy algorithm

Otherwise, skip the current item and process the next. We should stop when knapsack is full or all items are scanned. All items are tested. Problem: Given the six items in the table below and a knapsack with weight limit , what is the solution to this knapsack problem? We check the feasibility of item, if the inclusion of an item does not cross the knapsack capacity, we add it. Otherwise, we skip the current item and process the next. All items are scanned.

Greedy algorithms are used to find an optimal or near-optimal solution to many real-life problems. A few of them are listed below :. Share This Story!

With the same analysis of the second example, you have the result: select package 4 3 times and package 5 3 times. The algorithm of Greedy Three resolves quickly and can also be optimal in some cases. However, in some special cases, it does not give the optimal solution.
