A: While that is a really interesting note that I hadn’t spotted before, the standard formulation of exploration steps in logical inductor decision theory involve infinite exploration steps over all time, so even though an agent of this type would be able to inductively learn from what other agents do in different decision problems in less time than it naively appears, that wouldn’t make it explore less.

B: What I intended with the remark about Thompson sampling was that troll bridge functions on there being two distinct causes of “attempting to cross the bridge”. One is crossing because you believe it to be the best action, and the other is crossing because an exploration step occurred, and Thompson sampling doesn’t have a split decision criterion like this. Although now that you point it out, it is possible to make a Thompson sampling variant where the troll blows up the bridge when “crossing the bridge” is not the highest-ranked action.
