Hi @fhueske, the PR has been updated. However, there are still some
unfinished tasks, e.g., optimise the data caching and cleaning up policies and
distinguish the `<` and `<=`signs. I want to leave them as future works. What
do you think?
BTW, I find most of the recent PRs are failed on the build jobs with `TEST
= "misc"`. I'm not sure if there exist some problems with the CI. Here is a
