SPFA twice. Calculates the sum of the least short circuit between the come and the return. Using Dijkstra + adjacent matrix is indeed easy to write + easy to exchange, but there are 1000000 points, and the matrix cannot be opened. D1 [] is 1 ~ N. Swap the neighboring points of all edges. D2 [] is 1 ~ N. All are added as the desired answer. Sadly, SPFA "HDU 1535" AC is used, but POJ 1511 is the same as POJ. Then the obsessive-compulsive disorder kee

Test instructions: There is a starting site, from here to send n students to the rest of the N-1 site invite people to CSS, and then back to the CSS, so that the total cost is minimal. Note that you can only send one at a time, return each time can only send one, and each road is one-way.Analysis: This is equivalent to a graph, we only need to call the SPFA algorithm two times, the first time to find out the initial site (here is 1) to the minimum cost of all other sites, and then add, the secon

http://acm.hdu.edu.cn/showproblem.php?pid=1535 Main topic: The shortest path from 1 to any point and the shortest point to the starting point 1 Problem-solving ideas: a positive composition to find the shortest way, and then the direction of the map to change, reverse composition and then find the shortest way, the last two times accumulated and on the line. Considering the amount of data to the point, Dijkstra need to use priority queue optimization.

This section describes the running and structure of OOM killer. The out of memory (OOM) killer function in Linux serves as the final means to ensure the memory. After the system memory or swap zone is exhausted, it can send signals to the process and forcibly terminate the process. This function can ensure that the memory processing process is repeated even if the memory cannot be released to prevent system
