title: Top Packages Algorithm
|
|
|
|
## Pseudo rolling average
|
|
|
|
Every package loses 5% of its score every day.
|
|
|
|
An open source package will gain 1 score for each unique download,
|
|
whereas a non-free package will only gain 0.1 score.
|
|
|
|
A package currently only gains score through downloads.
|
|
In the future, a package will also gain score through reviews.
|
|
|
|
## Seeded using a legacy heuristic
|
|
|
|
The scoring system was seeded (ie: the scores were initially set to) 20% of an
|
|
arbitrary legacy heuristic that was previously used to rank packages.
|
|
|
|
This legacy heuristic is as follows:
|
|
|
|
forum_score = views / max(years_since_creation, 2 weeks) + 80*clamp(months, 0.5, 6)
|
|
forum_bonus = views + posts
|
|
|
|
multiplier = 1
|
|
if no screenshot:
|
|
multiplier *= 0.8
|
|
if not foss:
|
|
multiplier *= 0.1
|
|
|
|
score = multiplier * (max(downloads, forum_score * 0.6) + forum_bonus)
|
|
|
|
As said, this legacy score is no longer used when ranking mods.
|
|
It was only used to provide an initial score for the rolling average,
|
|
which was 20% of the above value.
|
|
|
|
## Transparency and Feedback
|
|
|
|
You can see all scores using the [scores REST API](/api/scores/).
