| Aug 31, 2018 at 20:10 | comment | added | DukeZhou | That conforms to my assumption (re: lookahead/planning) and I like your definition. I was recently thinking about asking a question on a formal terminological distinction between agents that only evaluate the present state and agents that look ahead. (Just for fun, I've considered Promethean functions which lookahead vs. Epimethian functions which can only utilize history in the form of the present state. "Forethought" vs. "Hindsight";) | |

I want to say "using a fixed amount of computation", but then a search algorithm with a fixed search depth could also be viewed as a "reflex agent"... so I guess it's difficult to actually get a solid, formal definition there. I guess roughly the "idea" of what I mean is clear though, even if it's difficult to formalize. | |
| Aug 31, 2018 at 20:00 | comment | added | Dennis Soemers♦ | @DukeZhou Well I suppose we don't really have a solid definition of what a "reflex agent is". My personal definition would pretty much be... an agent that doesn't involve planning / lookahead search. That could range from very simple heuristic / scripted / rule-based agents, all the way to complex agents that compute their policy through a fixed-architecture trained Neural Network (with the exception being Recurrent Neural Networks, since those in theory might be able to "learn" how to execute a planning algorithm in their black box) | |
| Aug 31, 2018 at 19:57 | comment | added | DukeZhou | Can I ask, is the idea here re: reflex agents, that the agent has more information than it is utilizing to make the decision? | |
| Aug 31, 2018 at 19:56 | comment | added | DukeZhou | I try to reinforce the point that we can only know that AlphaGo played more optimally than Lee Sedol in 4/5 games, but that objectively optimal play in Go may be ultimately indeterminable. | |
