4.3背包问题 (Knapsack Problem) 背包问题是一类经典的动态规划问题。给定一组物品,每个物品有重量w[i]和价值v[i],以及一个容量为W的背包,要求选择若干物品放入背包,使得总重量不超过W,且总价值最大。 状态定义:dp[i][j]表示从前i个物品中选择,且总重量不超过j时的最大价值。
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 types of knapsack that has been discussed so far is only to maximize the use not to exceed the limits specified capacity so it cannot be applied to the problem. This study aims to develop a dynamic programming algorithm to solve the MinMax 0/1 knapsack, which is an extension of the ...
A methodology using dynamic programming technique has been introduced in this paper with an algorithm which gives the optimal solution for single objective fuzzy knapsack problem (FKP) with some possibility. Using this methodology an algorithm is given to find the Pareto frontier in case of bi-...

Dynamic Programming 的基本思想:把原始问题划分成一系列子问题,自底向上计算 ,求解每个子问题仅一次,并将其结果保留在一 个表中,以后用到时直接存取,不用重复计算,节省时间。 适用范围: 一类优化问题:可分为多个相关子问题,子问题的解被重复使用。 动态规划方法: ...
The Knapsack Problem with Setup (KPS) is a generalization of the classical Knapsack problem (KP), where items are divided into families. An individual item can be selected only if a setup is incurred for the family to which it belongs. This paper provides a dynamic programming (DP) algorithm...
