"Backpack Ninth Lecture"p01:01 knapsack problemTopicThere are n items and a backpack with a capacity of V. The cost of article I is c[i], the value is w[i]. The solution of which items are loaded into the backpack allows the sum of the costs of these items to be no more than the backpack capacity and the maximum value.

Knapsack problem is a typical DP problem, and almost all types of knapsack problems can be converted to DP operations.p01:01 knapsack problemTopicThere are n items and a backpack with a capacity of V, the cost of the article I is c[i], the value is w[i], only one piece of each item, the solution will be loaded into the backpack of the items can not exceed the total cost of the

P01: 01 question about backpack There are n items and a backpack with a capacity of v. The cost of the I-th item is C [I], and the value is W [I]. Solving which items are loaded into a backpack can maximize the total value.Basic Ideas This is the most basic problem with a backpack. It features that each item has only o

Before this question, we will analyze two common backpack problems: 01 backpack and full backpack, 01 backpack: Take out several items from m items and put them in the backpack, volume of each item V1, V2, V3 ,.... the values are W1, W2, W3, and one item for each item. Solut

mentioned in section 9 are essentially two models: the 01 model and the full model. You can understand the two models thoroughly and then look at other models. This will definitely get twice the result with half the effort. A special topic was introduced during the course of reading the 9-pack lecture. There were about 26 topics, mainly HDU and poj, which were difficult and easy to answer. This album mainly explained these questions, there are also some simple questions about the UVA

If the question only requires the value of the optimal solution, step 5 can be omitted. Backpack Problems 01 backpack: There are n items and a backpack weighing M. (Each item on

Packet backpack, a condition evolved from the base backpack. The specific question is this. The specific question is this. A backpack with a capacity of V, and several sets of items, each containing a number of items, which are different, and volume W and value p are different. Objects in the group conflict. The maximum value can be obtained in the case of no

This is a problem in our homework, but also I think it is a very fun problem, is a bare multi-backpack, but it is only simple let me judge whether to fill. My first time in the tle, I thought the data of the homework problem is not very strong, simply stole a lazy enumeration of the number of the next selection, no binary optimization directly timed out, underestimated the teacher ~ so I added a binary optimization, experienced a bumpy before.About th

One, what is 01 backpack 　　01 The backpack is a few pieces of m items in the space W backpack, each item volume of W1,W2 to WN, corresponding to the value of P1,P2 to PN. 01 Backpack is the simplest problem in knapsack problem. 01 Backpack Constraints are given a fe

01 Backpack (Zeroonepack): There are n items and a backpack with a capacity of V, each of which has only one item . The cost of article I is c[i], the value is w[i]. The sum of the values is maximized by solving which items are loaded into the backpack.Full Backpack (completepack): There are n items and a backpack wit

P01 01 Backpacktopics There are n items and a backpack with a capacity of V. The cost of article I is c[i], the value is w[i]. The sum of the values is maximized by solving which items are loaded into the backpack. Basic Ideas The equation of state transfer is:f[i][v]=max{f[i-1][v],f[i-1][v-c[i]]+w[i]}This equation is very important, and basically all the equations for knapsack-related problems are derive

exceed the maximum value of volume m, the state transfer equation is:DP[I][J] = 0 (i==0orj==0)//no items, backpack volume of the largest value is also 0, and more items, backpack volume of 0 are not fit.DP[I][J]=DP[I-1][J] (JDp[i][j]=max (Dp[i-1][j],dp[i-1][j-d[i]]+w[i])//Current backpack If you can load the first item, then the maximum value after loading the a

Title Link: Http://codeforces.com/problemset/problem/946/DThe main topic: There are n strings, representing the N-day timetable, 1 indicates that the time to class, 0 means not to class, one day in school time for the first class to the last class time. In total, you can escape the K-class and ask for at least how much time you need at school.Problem-solving ideas: Listen to the big guy said backpack, and then pre-treatment think for more than 20 minu

There are n items, the first item (i = 1,2,3...N) is the value of VI, the weight is WI, we have a load-bearing for m backpack, we choose some items into the backpack, each can only put one, obviously put the total weight of the backpack not more than M. We ask to choose the total value of the item is the largest, please ask how to choose. Here we assume that all

Introduction: I love and hate backpacks and understand the code, but it does not mean that you have mastered backpacks. I know that modeling is difficult! So I am cheering for my backpack headache. perseverance can overcome all problems. Dynamic Planning is the abstraction of a method for changing the space for time. The key is to discover sub-problems and record their results. Then use these results to reduce the computational workload.For example,
