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...
Because the value and size of items and the size of knapsack can change along with the time, it causes that solving this problem is more difficult. We proposed an efficient algorithm for solving RTVKP with dynamic size of knapsack based on dynamic programming method, and analyzed the ...
The knapsack problem is an optimization problem used to illustrate both problem and solution. It derives its name from a scenario where one is constrained in the number of items that can be placed inside a fixed-size knapsack. Given a set of items with specific weights and values, the aim ...

knapsack problem Knapsack Problems I.History 1.1Introduction Knapsack Problems have been intensively studied since the pioneering work of Dantzig in the late 50’s, both because of their immediate applications in industry and financial management, but more pronounced for theoretical reasons, as Knapsack...
In the LPP(Linear programming problem) form, it can be described as: So this Knapsack problem can be solved by using these following methods: Greedy method Dynamic Programming method Back Tracking method Branch & Bound Greedy Method A greedy algorithm is an algorithm that follows the problem solv...
A logarithmic descent direction algorithm for the quadratic knapsack problem 8.1 Introduction The famous quadratic knapsack optimization problem introduced in [1] aims to obtain an optimal solution from a quadratic objective function subject to a knapsack constraint and has many applications, such as the...
In this article, we are going to learn about fractional knapsack problem. Algorithm for fractional knapsack with its example is also prescribed in this article.

We show that the simple unbounded knapsack problem, where the size of each item is equal to its value, allows for a competitive ratio of 2. We also analyze randomized algorithms and show that, in contrast to the 0-1 knapsack problem, one uniformly random bit cannot improve an algorithm’s...
