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...

Therefore, interest in the application of the metaheuristic algorithms has become necessary to solve these problems and obtain the results in a reasonable time [19–22]. The 0–1 KP can be solved also by greedy genetic algorithm (GA), GA, and rough set theory and ant weight-lifting ...

Pros: Simplicity and Speed: The greedy approach is straightforward and fast. Cons: I applicability: This method doesn't work for the 0/1 knapsack because taking fractions of items isn't allowed. Verified Reviewer Technical Consultant Information Technology and Services, 11-50 employees Used the ...

It is one of the most popular problems that take greedy approach to be solved. It is called as the Fractional Knapsack Problem.To explain this problem a little easier, consider a test with 12 questions, 10 marks each, out of which only 10 should be attempted to get the maximum mark of...
Prerequisites: Algorithm for fractional knapsack problemHere, we are discussing the practical implementation of the fractional knapsack problem. It can be solved using the greedy approach and in fractional knapsack problem, we can break items i.e we can take a fraction of an item. For examples, ...
Greedy LP-GMKP Algorithm Proposition 1 Optimal extreme points of an LP-GMKP instance can have more than one partially assigned group. Proof of Proposition 1 Consider the case with two knapsacks of capacities{c_1=3}and{c_2=1}, and two groups with rewardsp_1=p_2=3. The first group has...
