Any part of the enviroment that is fully observable is called a fully obersable
enviroment. Else it is partially observalble. Most aspects of the enviroment
are only partially observable.
A stocahstic enviroment is random in nature and cannot be determined completely
by an agent.
In a deterministic enviroment that is fully obersvable, agents do not need to
account for random chance.
If the enviroment can change while the agent is deliberating/computing what to
do, then the enviroment is dynamic. Otherwise, it is static. Static enviroments
are much easier to deal with, because an agent must not constantly deliberate
on when to change course suddenly.
If the number of possible states that can be percieved is bounded, then the
enviroment is called a discrete enviroment, otherwise it is a continous
enviroment. A chess game is discrete, because there is a finite number of moves
that cna be played.
If there is only one agent in the enviroment, then it is called a single agent
enviroment. HOwever if mulitple agents are operating in the enviroment, then it
is a multi agent enviroment. The design problems are much harder in a
multiagent enviroment.
