问HN：不稳定的HN首页算法
上周，我的两篇投稿登上了HN的首页。在此之前，我认为一篇帖子在达到顶峰后，其排名会遵循大致单调递减的时间衰减曲线。然而，在观察这两篇帖子时，我注意到了一些不同的情况：它们的排名有时在下降后会有所提升，并且偶尔会来回波动（这里有一张显示这种行为的图表：https://imgur.com/a/AQnSh6I）。HN排名算法中有哪些机制导致了这种非单调的变化？是由于投票权重、评论活动、重新排名批次，还是其他原因？

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
