How do 1 and -1 reward be used? about deeplearningflappybird

@guotong1988 I do not quite understand your question. But every transition is recorded as a 4 element tuple in the deque. You should note that the reward is a instant reflection of the environment. I really think you should learn the very basic concept of Markov Reward Process and Markov Decision Process first before reinforcement learning.

看这里，reward为1和-1都只能被sample出来然后feed进去，这样只有被sample出来才能起作用

@guotong1988 i see, you are right, thus the author implied that prioritized experience replay can potentially optimize your problem by improving the probability of a more significant transition being chosen in another issue.
