tried to select N points, the step size reduced by 1/10 each time, and the precision was controlled at 1e-3. Actually, TLE, I read so much online code. Then start various attempts to reduce the number of selected points. Various Wa and TLE languages... A good acmer gave a set of data 4 0 0 0 2 2 2 2 0 1 Generally, if the accuracy is too high during the determination, this set of data will not be able to pa

Let's review the largest stream at that time .. Try again... I don't want to talk about the classic solution anymore .. This question mainly refers to the pitfall time, with 10 submissions of 7 TLE. Ring judgment, once using a simple DFS method, this time it's TLE! I felt that I could not time out to use a very embarrassing dinic. I firmly believed that the ring was slow. So I learned how to delete a vertex

what he is doing, but I haven't started to submit it yet. Then I looked at the second smallest difference, and it was not difficult to feel myself. I decided to do this. When I first wanted to write it, a contestant came over and I knew that I was sitting in another place .... Immediately return the location to someone else and use the computer on the right, that is, the computer where I was originally located. Continue with the second question. The code for the second question was quickly com

Http://poj.org/problem? Id = 2823 Basic monotonous queue. The deque of STL is actually TLE !!! Whether C ++ or G ++... The array is used to submit C ++ AC. Submitting g ++ TLE doesn't understand why. Heap operation: first, perform operations on the tail. Take a small root heap as an example: When an element is added from the tail, check whether there is a bigger one than the former, and delete the former, t

[Preface] ttvtt asked me to WHL and then ...... After 5 rounds of WA, 6 rounds of RE, and 3 rounds of TLE, I finally broke down with this question. A tree provides an edge weight. There are two operations: change the value of an edge and find the maximum edge weight from path a to path B. [Click it] This is a good training question for tree link splitting and edge partitioning. However, the data seems abnormal and easy to look like

Maximum stream of hdu 4975 and determination of its uniqueness (directed graph ring judgment algorithm upgrade) Let's review the largest stream at that time .. Try again... I don't want to talk about the classic solution anymore .. This question mainly refers to the pitfall time, with 10 submissions of 7 tle. Ring judgment, once using a simple dfs method, this time it's tle! I felt that I could not time out

during the school period, at that time compared to naive is also want to simulate the idea is the head of the reverse array reversed to go, and then the wit to tle. Suddenly want to come back to do this problem, of course, or simulation, the idea is to continue to go beyond the range, and then the current POS symmetrical back, a kind of folding feeling ... It turns out that the method is feasible, but how can the circulating volume of a

This is a good topic ah, holiday back ready to practice practiced hand, found that I was weak explosion ... First of all, the general determination of the idea, drew a while, found that the priority queue directly greedy can, then knocked, started with a string led has been WA, did an afternoon, and then found the wrong place, then the tle, and then see Online said is not using the STL priority queue, I write a small heap, and then set up a template,

noon, has been tle, code in the back post, after watching the great God's blog know where the reason for the timeout, each number of the quality factor can be in the table to find Euler function when the way out, a hash of the idea, so do not have in the enumeration of each number in the request for his quality factor, good problem!The code is as follows: (608MS)#include #include#includestring.h>#include#include#includeusing namespacestd;typedef __in

If we want to obtain a sub-sequence that satisfies yi + YJ Method: Consider O (N)Algorithm, Directly brute force, and then obtain the answer. ... Tle .... It seems that the force is not good ~ Consider nonviolence ~~~ First, calculate the cyclic section cyclically, and record whether there is a value beyond l/2. Then, calculate the part that exceeds the cyclic section by skipping the cyclic section. This is also

This question is a naked query of the Euler's function, but the result is a tragedy, TLE. # Include Then I typed a method for listing prime numbers, and determined their common divisor one by one. The result was TLE. # Include Then I can't do Baidu. I thought of the Phi (Mn) = PHI (m) * PHI (n) method when I saw someone talking about using the Euler's function, but I didn't expect
