Then sort these ratios with descending order. You will choose the highest package and the capacity of the knapsack can contain that package (remain > w i). Every time a package is put into the knapsack, it will also reduce the capacity of the knapsack. Way to select the The knapsack problem is one of the most studied problems in combinatorial optimization, with many real-life applications. For this reason, many special cases and generalizations have been examined. Common to all versions are a set of n items, with each item having an associated profit pj,weight wj.
