It is characterized by the user can vote in favour of the vote, can also vote against. In other words, in addition to the time factor, just consider two variables is enough. However, there are a number of specific uses of the site, you must consider more factors. The world's number one programmer question and answer commun

The user's global ranking is similar, only need: Zrank leaderboard A common variant of the list, like Reddit or hacker news, is sorted by score according to a formula similar to the following:Score = Points/time^alpha So the user's vote will be the corresponding to dig out the news, but the time will be according to a certain index will bury the news. Here is our pattern, of course the algorithm is up to you. The pattern is this, th
