Hello organisers, One component of our ranking workflow is our own reimplementation, written from the published method text of another participating group's write-up in this project, of the ranking approach that group described. No output or candidate list of theirs is used, only the prose recipe, and the component is credited to its authors in our submission write-up. Is such a reimplementation permitted, and is a submission that contains it eligible, or do the challenge rules treat it as derived from another participant's submission? Thank you.
