Deep Q-Networks are effective in a variety of high-dimensional observation spaces, as evidenced by performance on a variety of tasks such as Atari.. Rule 12, Section 3, Article 6 (c) allows for replay to review game clock at end of a period. . If there is a significant mistake related to the game clock replay can fix regardless of review. . END OF PERIOD.
