Depth Limited search in Pluribus

[CloneHub94]

Hi guys

I just had a question related to how the depth limit of a subgame is determined.
This seems to be something I can't quite figure out.
Is it always a depth-limit of 1?

I was wondering if you might be able to enlighten me on how exactly the depth limit of subgames for Pluribus gets determined during real-time search and wherein the literature I could find this information?

Thanks in advance

I have no idea how this particular software implements it, but the Pluribus paper references this other research paper about depth-limited solving for imperfect information games.
