"In the study of computational complexity, we often find that the boundaries of what is possible are defined by the limits of our imagination."

Every one is their God,if you give up on yourself,who else will save you?Every one is busy,some are busy livig,some are busy dying,and you, who are busy chasing fame and fortune,who are busy with daily necessities,try to stop to think a second:if your brain has been institutionalized?Where is your God?

绝不能为了速度而牺牲质量。
