Deterministic vs. static environments
Does for a given environment e
“e deterministic => e static”
hold?


No, that does not hold in general. A static environment does not change. A deterministic environment may change but the change is completely determined by the last state and the action of the agent. For example large scale physical environments are so regular that they can often be considered to be deterministic. The solar system is highly dynamic - at different times the planets are at completely different positions - but their change is so regular that given a single state you can make accurate predictions about the future - which is why astronomy was one of the first disciplines that was studied in a scientific way, for example by the ancient Babylonians and Maya.


Thank you for your answer! From our definition of “static” on the slides (quote: “dynamic, iff the environment can change without an action performed by a, else static”) I got the impression that static environments may change, just not without an action from a.


Correct, or in other words: the only way a static environment can change is through an action by the agent. Compare again the solar system where actions of any (realistic) agent have basically no effect on the environment.
