And implemented this algorithm in Python: 274520784 However, this code WAs for test case 8, with my answer of 11 being higher than the expected answer of 9. I have read the editorial for this question, and I believe the DP formula in the editorial is the same as my DP formula mentioned...
1. 贪婪算法(Greedy algorithm):贪心算法是一种简单的算法,它总是选择当前最优解,而不考虑整体最优解。在分数背包问题中,贪心算法会选择当前总价值最大的物品放入背包。在0-1背包问题中,贪心算法会选择当前总重量最小的物品放入背包。 def greedy_algorithm(items, capacity): # 计算每个物品的重量和价值 weights...

Greedy algorithm for a knapsack problem with the example of Robbery in PythonHere, we will learn to use greedy algorithm for a knapsack problem with the example of Robbery using Python program. Submitted by Anuj Singh, on May 12, 2020 ...
Following is the final implementation of Fractional Knapsack Algorithm using Greedy Approach −C C++ Java Python Open Compiler #include <stdio.h> int n = 5; int p[10] = {3, 3, 2, 5, 1}; int w[10] = {10, 15, 10, 12, 8}; int W = 10; int main(){ int cur_w; float...

Algorithm for fractional knapsack 1. W and item have value Viand weight Wi. 2. Rank item by value/weight ratio: Vi/Wi. 3. Thus : Vi/Wi= Vj/Wjfor all i<=Wj. 4. Consider items in order of descending ratio. 5. Take as much of each item is possible. 6. Assume value and weight...
An alternative to using optimization is a greedy algorithm where the items are successively selected based on a metric such as the highest value to weight ratio. This is done until the weight limit is exceeded. While this approach is computationally fast and intuitive, it may give suboptimal ...
