Now whatever the relational network data size is very large, such as the https://snap.stanford.edu/data/above the public data set, is still tens of thousands of nodes, a hundred thousand of sides. However, some of the laws behind the big picture data highlight the nature of the value of Big Data discovery. This blog in the last community to undertake the problem of discovery, continue in the large-scale relationship

I just watched the social network. It is almost the networked version of the doom revelation, although idsoftware has not achieved such a big commercial profit as Facebook and brought the impact to the world. However, the main character is a kind of people, which are very similar. It may be because of the environmental impact of the day after tomorrow, perhaps because of the natural asberger syndrome pat

This problem is one of the Chengdu Regional Competition online game.This idea is very easy, but from time to consider, may not use matrix storage, I use the chain forward to the star.Use the online query. It is very convenient to use map to number strings. To recommend a friend, is actually a friend of friends (here refers to direct friends, the figure refers to the direct side of the link).So when looking, just need to find friends, and count.Note: You cannot have a space for the output.Attache

Transmission DoorThe shortest-circuit count problem. Because the amount of data is very small ($N \leq 100$), so Floyd do it casually.$f [i][j]$ represents the path length, $g [i][j]$ represents the maximum number of short-circuit scenarios.Run the bare Floyd first, then use the multiplication principle to count the $g[i][j]$.$g [i][j]=\sum g[i][k] \times g[k][j]$Bzoj 1491//by cydiater//2016.10.27#include BZOJ1491: [NOI2007] Social
