@NeilSlater I have asked a few questions on RL here (as you know), but only because I think there aren't enough competent people visiting the website https://ai.stackexchange.com/. I don't like much the philosophy and political guidance of that website. For example, they haven't yet enabled Latex support for the posts, they have allowed questions and answers which are highly based on opinions, etc. Honestly, I think, RL is the most characterizing sub-field of AI.

It's a pity I have to ask questions about RL here or on stats, given that there exists already a website dedicated to AI.
