Environment types
l Fully observable (vs. partially observable): An agent's
sensors give it access to the complete state of the
environment at each point in time.
l Deterministic (vs. stochastic): The next state of the
environment is completely determined by the current
state and the action executed by the agent. (If the
environment is deterministic except for the actions of
other agents, then the environment is strategic)
l Episodic (vs. sequential): The agent's experience is
divided into atomic "episodes" (each episode consists of
the agent perceiving and then performing a single
action), and the choice of action in each episode
depends only on the episode itself.
