投票算法:如何计算等级? [英] Voting algorithm: how to calculate rank?

问题描述

我正在尝试找出一种计算排名的方法.现在，它只需要计算每个单独条目的赢/输比，例如一个人赢了100次中的99次，它的获胜率是99％.但是，如果某项在1票中赢得1票，它将获得100％的获胜排名，但绝对不能比赢得99次的那位更高.有什么更好的方法可以做到这一点?

I am trying to figure our a way to calculate rank. Right now it simply takes ratio of wins / losses of each individual entry, so e.g. one won 99 times out of a 100, it has 99% winning rank. BUT if an entry won 1 out of total 1 votes, it will have a 100% winning rank, but definitely it can't be higher that of the one that won 99 times. What would be a better way to do this?

推荐答案

根据您想要制作的复杂程度，Elo系统国际象棋使用(或类似的方式)可能是您想要的:

Depending on how complicated you want to make it, the Elo system chess uses (or something similar) may be what you want: http://en.wikipedia.org/wiki/Elo_rating_system

例如，即使一个人赢得了1/1场比赛，他的评分也将远低于在艰难的对手中赢得/输掉数百场比赛的人.

Even if a person has won 1/1 matches, his rating would be far below someone who has won/lost hundreds of matches against tough opponents, for instance.
