POJ 3181 Dollar Dayz 01 full backpack problem, pojdayz 01 A complete backpack problem. This mainly describes the number of combinations. There are more people doing two-dimensional dp. here we can use one-dimensional dp. One-dimensional transformation equation: dp [j] = dp [j-I] + dp [j]; where I represents the weight and j represents the current backpack capaci

First, sort the first n-1 from small to large, carry 01 backpack on the M-5, then the answer is m-DP [M-5]-A [n-1]As for why the most expensive food was last removed, rather than putting the most expensive food into the 01 backpack,Because if you can put the most expensive dish a [n-1] can be put in the backpack, then other dishes a [I] can certainly be placed in

Problem: Assume that there are n items, each item has weight, and each item is also valuable. To put these items in a backpack, the carrying capacity of this backpack is limited, how can we maximize the total value of items in a backpack? Symbol: N: number of items W: carrying weight of a backpack W [I]: Weight of ite

Method recursively searches in the solution space until the required solution or solution space has no dynamic knots. (2) solving 0-1 knapsack algorithm analysis The 0-1 knapsack problem is the subset selection problem. Generally, the 0-1 backpack problem is NP-hard. The solution space of the 0-1 knapsack problem can be represented by a subset tree. When searching for a spatial tree, as long as its left son node is a feasible node, the search enters

Question: Click to open the link Question: There are n items, each of which has two attributes: volume and value. A thief carries a V-sized backpack and wants to steal these items, q: What is the maximum value of K that thieves can steal? Ideas: This is different from the typical 01 backpack to find the optimal solution. It requires a K-level solution. Therefore, the most intuitive idea is to add one dim

Question: poj 2484 cow Exhibition Question: Give the nheaded ox. Each ox has a lucky Si and a smart ti. Now we need to select some cows to maximize the sum of the two values, provided that sum (SI) and sum (Ti) are both non-negative values. Analysis: The data volume of this question is small, and it can be searched and trimmed. Here we will talk about the idea of a 0-1 backpack. The obvious deformation of this question is that the item has two attri

There is a virtual root 0, and cost is required to take this virtual root, so the final result is DP [0] [M + 1]. This is a special backpack problem with cost = 1. There is an optimization on two for loops. For (F + 1... j

First, you need to calculate the total value of the N devices. The two schools are equally divided as much as possible. If the average score is not completely equal, the first school should be divided into one more point. Q: How many valuable devices can the two schools share?
