Poj (2184) -- Cow Exhibition (01 backpack deformation) In fact, I don't think I have a deep understanding of this question. However, after doing this today, we will first record our current ideas. The general meaning of the question is: There is a nheaded ox, each of which has a s value representing the IQ value, and a f value representing its humorous value. Then, ask you what the total and maximum values of the IQ and humor values are, and ensure th

There are n items and a backpack with a capacity of M, with unlimited pieces available for each item. The volume of the article I is weight, and the value is values. The solution of which items are loaded into the backpack allows the volume of these items to be no more than the backpack capacity, and the value of the largest sum.1 //"n" is the number of kinds.2 /

This question is about money-saving pig, empty quality W1, money quality W2, and then the value and weight of various types of money, asking how much money a piggy bank needs to store is a classic topic for getting started with a full backpack. Now I don't fully understand it. Let's talk about my understanding. The full backpack is to put every kind of data in it as much as possible, and every kind of data

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
