As far as I can tell from wikipedia’s description of admissibility, it makes the same assumptions as CDT: That the outcome depends only on your action and the state of the environment, and not on any other properties of your algorithm. This assumption fails in multi-player games.
So your quote actually means: If you’re going to use CDT then Bayes is the optimal way to derive your probabilities.
