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...

This is an optimization problem in which we have to optimize the overall quantified value by selecting the best items to steal within his bag. The bag can have a maximum volume of 54 Liters.Program:# Greedy Algorithm for a Robbery # Defined a class for items, with # its name, val...
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 ...
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...
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, ...
