提问 HN：HN 前台页面算法不稳定
2 分•作者: 7777777phil•6 个月前
上周，我提交的两篇文章都登上了 HN 首页。在那之前，我一直以为文章的排名在达到峰值后，会遵循一个大致单调的时间衰减曲线。但在观察这两篇文章时，我注意到了一些不同的现象：它们的排名有时会在下降后回升，偶尔还会来回震荡（这里有一个展示这种行为的图表：https://imgur.com/a/AQnSh6I）。是什么 HN 排名算法中的机制导致了这种非单调的波动？是投票权重、评论活动、重新排名批次，还是其他什么原因？

Last week I had two submissions reach the HN front page. Before that, I assumed the ranking followed a roughly monotonic time-decay curve once a post peaked. While watching these two posts, I noticed something different: their rank would sometimes improve after declining, and occasionally oscillate back and forth (Here is a graph showing this behavior: https://imgur.com/a/AQnSh6I). what mechanisms in the HN ranking algorithm cause this kind of non-monotonic movement. Is it due to vote weighting, comment activity, re-ranking batches, or something else?<p>The graph is from: https://track-hacker-news.com/<p>EDIT: This is the post referenced: https://news.ycombinator.com/item?id=46512881
