What is terminal state?
Terminal state: A situation in which a run ends and no further choices or scores follow. Its value is defined as zero, which stops the recursive value calculation. Reaching one may be good, such as a win, or bad, such as a crash.
Terminal state: an example
In a maze task, the exit square is terminal; stepping into a trap square may also be terminal with reward -10.
