There is a 27 cm fine wood rod, in the 3rd centimeter, 7 cm, 11 cm, 18 cm, 23 cm, each of the five positions have an ant. The wooden rod is very thin and cannot pass through two ants at the same time. At first, the ants head to the left or to the right is arbitrary, they will only go forward or turn around, but will not retreat. When any two ants meet, two ants will turn around in the opposite direction at

Steel bar Cutting problem: Given a length of n-inch steel bars and a price list pi (i=1,2,..., N) to cut the steel bar scheme, making the largest sales yield rn.Note that if the price pn is large enough for the length of the n-inch steel bar, the optimal solution may be that there is no need for cutting at all.Idea: First cut the steel bar into two pieces, there

Suddenly found that the steel bar cutting actually did not write.Suppose the company sells a piece of steel with a length of I-inch for the price of pi (i = 1, 2, ...). Unit: USD), below is a sample price list:Length I 1 2 3 4 5 6 7 8 9 10Price PI 1 5 8 9 10 17 17 20 24 30The problem with cutting steel bars is this: given a length of n-inch steel bars and a price

The first dynamic programming problem of algorithm introduction--Steel bar cuttingWe know the lengths and prices of steel rods are: Length I 1 2 3 4 5 6 7 8 9 10 Price PI 1 5 8 9 10 17 17 20 24 30 The two methods of the book are already very clear, here is mainly said after class after the practice of 15-3 steel

Looking at the dynamic programming (DP) in the introduction to the algorithm today, there is an interesting question: the steel strip cutting to get the maximum benefit.Several solutions are discussed, including recursive solution method, Memo DP solution, bottom-up solution and the reconstruction of the solution.The book gives the pseudo code of different solutions, just need to practice C + +, there is C + + to achieve DP solution to the steel bar

An introduction to the problem of steel bar cutting in reading notesQiao is clumsy (welcome reprint, but please specify Source: Http://blog.csdn.net/qiaoruozhuo )given a length of N inch of steel rods and a price list Pi (i=1,2, ..., n) , to cut the steel bar scheme, so that the sales proceeds RN Maximum. Note that if the length of the steel bar with an n -inch is large enough, the optimal solution may be

Dynamic planning, in fact, is similar to the division of the law, the basic idea is to divide the complex problem into a number of simple sub-problems, and then to solve. The difference is that the sub-problems concerned by the division and treatment do not overlap each other, while the sub-problems of dynamic planning are overlapping. For example, in the fast sort, we divide the data into two parts, the two parts of the recursive idea of the sorting

about full-screen games, like League of Legends, games, automatic cutting to the desktop problem, previously released a resolved issue. Today comes a similar question, of course, using the front-end process tool to find out what process is causing the game to be cut out. After observation for Update.exe this process is caused. Then you need to find the source of the file. By finding the path, it is found th

overlaps), the call can be positioned directly from the array. The redundancy and frequent recursive calls in the naïve solution are eliminated, and the time and memory space consumption is reduced.ARR is a mechanism for forgetting.The dual for loop guarantees the appearance of each case and is updated by continually calling the Max function to iterate Q. When each option is completed for the first time, it is logged by using the auxiliary memo array, arr, for the next occurrence of sub-

The beauty of programming is a light and shade cutting problem. After analysis, it can be simplified to a problem of finding the number of reverse orders. Of course, the number of reverse orders can be very violent O (N ^ 2) however, if you are taking an interview and give an O (N ^ 2) solution, the interviewer will not be satisfied with it, and the impression on

explanation is very exciting.And in order to output the scheme, the reconstruction solution is used to output.The code is as follows#include #include typedef struct CUT{int *r;int *s;}cut;void Initialize (Cut *mycut,int N){mycut->r= (int *) malloc (sizeof (int) *n);mycut->s= (int *) malloc (sizeof (int) *n);}cut* T (int p[],int N){Cut *mycut= (Cut *) malloc (sizeof (cut));Initialize (mycut,n);mycut->r[0]=0;for (int j=1;j{int q=int_min;for (int i=1;i{if (Q{q=p[i]+mycut->r[j-i];mycut->s[j]=i;}}my
